QUESTION 1You have an application that uses a view to access data from multiple tables. You need to ensure that you caninsert rows into the underlying tables by using the view. What should you do?

A. Materialize the view.B. Create an INSTEAD OF trigger on the view.C. Define the view by using the CHECK option.D. Define the view by using the SCHEMABINDING option.

Correct Answer: BSection: (none)Explanation

Explanation/Reference:References:http://msdn.microsoft.com/en-us/library/ms180800.aspxhttp://msdn.microsoft.com/en-us/library/ms187956.aspx

You can modify the data of an underlying base table through a view, as long as the following conditions aretrue:

Any modifications, including UPDATE, INSERT, and DELETE statements, must reference columns fromonly one base table.The columns being modified in the view must directly reference the underlying data in the table columns.The columns cannot be derived in any other way, such as through the following:

1. An aggregate function: AVG, COUNT, SUM, MIN, MAX, GROUPING, STDEV, STDEVP, VAR, and VARP.2. A computation. The column cannot be computed from an expression that uses other columns. Columns that

are formed by using the set operators UNION, UNION ALL, CROSSJOIN, EXCEPT, and INTERSECTamount to a computation and are also not updatable.The columns being modified are not affected by GROUP BY, HAVING, or DISTINCT clauses.TOP is not used anywhere in the select_statement of the view together with the WITH CHECK OPTIONclause.

Materialize the view.In SQL this is an indexed view

CHECK OPTIONForces all data modification statements executed against the view to follow the criteria set withinselect_statement. When a row is modified through a view, the WITH CHECK OPTION makes sure the dataremains visible through the view after the modification is committed. Any updates performed directly to a view'sunderlying tables are not verified against the view, even if CHECK OPTION is specified.

SCHEMABINDINGBinds the view to the schema of the underlying table or tables. When SCHEMABINDING is specified, the basetable or tables cannot be modified in a way that would affect the view definition. The view definition itself mustfirst be modified or dropped to remove dependencies on the table that is to be modified. When you useSCHEMABINDING, the select_statement must include the two-part names (schema.object) of tables, views, oruser-defined functions that are referenced. All referenced objects must be in the same database.Views or tables that participate in a view created with the SCHEMABINDING clause cannot be dropped unlessthat view is dropped or changed so that it no longer has schema binding. Otherwise, the Database Engineraises an error. Also, executing ALTER TABLE statements on tables that participate in views that have schemabinding fail when these statements affect the view definition.

If the previous restrictions prevent you from modifying data directly through a view, consider the followingoptions:INSTEAD OF Triggers

INSTEAD OF triggers can be created on a view to make a view updatable. The INSTEAD OF trigger isexecuted instead of the data modification statement on which the trigger is defined. This trigger lets the userspecify the set of actions that must happen to process the data modification statement. Therefore, if anINSTEAD OF trigger exists for a view on a specific data modification statement (INSERT, UPDATE, orDELETE), the corresponding view is updatable through that statement. For more information about INSTEADOF triggers, see DML Triggers.Partitioned ViewsIf the view is a partitioned view, the view is updatable, subject to certain restrictions. When it is needed, theDatabase Engine distinguishes local partitioned views as the views in which all participating tables and the vieware on the same instance of SQL Server, and distributed partitioned views as the views in which at least one ofthe tables in the view resides on a different or remote server.

Conditions for Modifying Data in Partitioned ViewsThe following restrictions apply to statements that modify data in partitioned views:The INSERT statement must supply values for all the columns in the view, even if the underlying membertables have a DEFAULT constraint for those columns or if they allow for null values. For those member tablecolumns that have DEFAULT definitions, the statements cannot explicitly use the keyword DEFAULT.The value being inserted into the partitioning column should satisfy at least one of the underlying constraints;otherwise, the insert action will fail with a constraint violation.UPDATE statements cannot specify the DEFAULT keyword as a value in the SET clause, even if the columnhas a DEFAULT value defined in the corresponding member table.Columns in the view that are an identity column in one or more of the member tables cannot be modified byusing an INSERT or UPDATE statement.If one of the member tables contains a timestamp column, the data cannot be modified by using an INSERT orUPDATE statement.If one of the member tables contains a trigger or an ON UPDATE CASCADE/SET NULL/SET DEFAULT or ONDELETE CASCADE/SET NULL/SET DEFAULT constraint, the view cannot be modified.INSERT, UPDATE, and DELETE actions against a partitioned view are not allowed if there is a self-join with thesame view or with any of the member tables in the statement.Bulk importing data into a partitioned view is unsupported by bcp or the BULK INSERT and INSERT ... SELECT* FROM OPENROWSET(BULK...) statements. However, you can insert multiple rows into a partitioned view byusing the INSERT statement.NoteTo update a partitioned view, the user must have INSERT, UPDATE, and DELETE permissions on the membertables.

QUESTION 2You create a view by using the following code:

Several months after you create the view, users report that the view has started to return unexpected results.You discover that the design of Table2 was modified since you created the view. You need to ensure that theview returns the correct results. Which code segment should you run?

A. EXEC sp_refreshview @viewname = 'dbo.View1';

B. ALTER dbo.View1 WITH SCHEMABINDING, VIEW_METADATAASSELECT t1.col1, t1.col2, t2.*FROM dbo.Table1 AS t1 JOIN dbo.Table2 AS t2ON t1.col1 = t2.col2;

C. DROP dbo.View1;GO

CREATE dbo.View1 WITH SCHEMABINDING, VIEW_METADATAAS SELECT t1.col1, t1.col2, t2.*FROM dbo.Table1 AS t1 JOIN dbo.Table2 AS t2ON t1.col1 = t2.col2;

D. EXEC sp_refreshsqlmodule @name = 'dbo.Table2';

Correct Answer: ASection: (none)Explanation

Explanation/Reference:References:http://msdn.microsoft.com/en-us/library/ms173846.aspxhttp://msdn.microsoft.com/en-us/library/ms187956.aspxhttp://msdn.microsoft.com/en-us/library/ms187821.aspxhttp://msdn.microsoft.com/en-us/library/bb326754.aspx

sp_refreshviewIf a view is not created with schemabinding, sp_refreshview should be run when changes are made to theobjects underlying the view that affect the definition of the view. Otherwise, the view might produce unexpectedresults when it is queried.

sp_refreshsqlmoduleUpdates the metadata for the specified non-schema-bound stored procedure, user-defined function, view, DMLtrigger, database-level DDL trigger, or server-level DDL trigger in the current database. Persistent metadata forthese objects, such as data types of parameters, can become outdated because of changes to their underlyingobjects.

sp_refreshsqlmodule should be run when changes are made to the objects underlying the module that affect itsdefinition. Otherwise, the module might produce unexpected results when it is queried or invoked. To refresh aview, you can use either sp_refreshsqlmodule or sp_refreshview with the same results.

ALTER ViewModifies a previously created view. This includes an indexed view. ALTER VIEW does not affect dependentstored procedures or triggers and does not change permissions.

SCHEMABINDINGBinds the view to the schema of the underlying table or tables. When SCHEMABINDING is specified, the basetables cannot be modified in a way that would affect the view definition. The view definition itself must first bemodified or dropped to remove dependencies on the table to be modified. When you use SCHEMABINDING,the select_statement must include the two-part names (schema.object) of tables, views, or user-definedfunctions that are referenced. All referenced objects must be in the same database.Views or tables that participate in a view created with the SCHEMABINDING clause cannot be dropped, unlessthat view is dropped or changed so that it no longer has schema binding. Otherwise, the Database Engineraises an error. Also, executing ALTER TABLE statements on tables that participate in views that have schemabinding fail if these statements affect the view definition.VIEW_METADATASpecifies that the instance of SQL Server will return to the DB-Library, ODBC, and OLE DB APIs the metadatainformation about the view, instead of the base table or tables, when browse-mode metadata is beingrequested for a query that references the view. Browse-mode metadata is additional metadata that the instanceof Database Engine returns to the client-side DB-Library, ODBC, and OLE DB APIs. This metadata enables theclient-side APIs to implement updatable client-side cursors. Browse-mode metadata includes information aboutthe base table that the columns in the result set belong to.For views created with VIEW_METADATA, the browse-mode metadata returns the view name and not thebase table names when it describes columns from the view in the result set.When a view is created by using WITH VIEW_METADATA, all its columns, except a timestamp column, areupdatable if the view has INSERT or UPDATE INSTEAD OF triggers. For more information, see the Remarkssection in CREATE VIEW (Transact-SQL).

QUESTION 4You have an index for a table in a SQL Azure database. The database is used for Online TransactionProcessing (OLTP). You discover that the index consumes more physical disk space than necessary. You needto minimize the amount of disk space that the index consumes. What should you set from the index options?

A. STATISTICS_NORECOMPUTE = OFFB. STATISTICS_NORECOMPUTE = ONC. FILLFACTOR = 0D. FILLFACTOR = 80

Correct Answer: CSection: (none)Explanation

Explanation/Reference:According to these references, this answer looks correct.

Reference: http://msdn.microsoft.com/en-us/library/ms177459.aspxhttp://msdn.microsoft.com/en-us/library/ms188783.aspx

FILLFACTORThis topic describes what fill factor is and how to specify a fill factor value on an index in SQL Server 2012 byusing SQL Server Management Studio or Transact-SQL.The fill-factor option is provided for fine-tuning index data storage and performance. When an index is createdor rebuilt, the fill-factor value determines the percentage of space on each leaf-level page to be filled with data,reserving the remainder on each page as free space for future growth. For example, specifying a fill-factorvalue of 80 means that 20 percent of each leaf-level page will be left empty, providing space for indexexpansion as data is added to the underlying table. The empty space is reserved between the index rows ratherthan at the end of the index.

The fill-factor value is a percentage from 1 to 100, and the server-wide default is 0 which means that theleaf-level pages are filled to capacity.Performance ConsiderationsPage SplitsA correctly chosen fill-factor value can reduce potential page splits by providing enough space for indexexpansion as data is added to the underlying table.When a new row is added to a full index page, the DatabaseEngine moves approximately half the rows to a new page to make room for the new row. This reorganization isknown as a page split. A page split makes room for new records, but can take time to perform and is aresource intensive operation. Also, it can cause fragmentation that causes increased I/O operations. Whenfrequent page splits occur, the index can be rebuilt by using a new or existing fill-factor value to redistribute thedata. For more information, see Reorganize and Rebuild Indexes.Although a low, nonzero fill-factor value may reduce the requirement to split pages as the index grows, theindex will require more storage space and can decrease read performance. Even for an application oriented formany insert and update operations, the number of database reads typically outnumber database writes by afactor of 5 to 10. Therefore, specifying a fill factor other than the default can decrease database readperformance by an amount inversely proportional to the fill-factor setting. For example, a fill-factor value of 50can cause database read performance to decrease by two times. Read performance is decreased because theindex contains more pages, therefore increasing the disk IO operations required to retrieve the data.Adding Data to the End of the TableA nonzero fill factor other than 0 or 100 can be good for performance if the new data is evenly distributedthroughout the table. However, if all the data is added to the end of the table, the empty space in the indexpages will not be filled. For example, if the index key column is an IDENTITY column, the key for new rows isalways increasing and the index rows are logically added to the end of the index. If existing rows will be updatedwith data that lengthens the size of the rows, use a fill factor of less than 100. The extra bytes on each page willhelp to minimize page splits caused by extra length in the rows.

STATISTICS_NORECOMPUTEQuestion: Recently I noticed an option with CREATE/ALTER INDEX called STATISTICS_NORECOMPUTE?I'm not sure I understand this option or why you'd ever want to use it? Can you explain?

Answer: In general, I don't recommend this option. But, before I get to why - let me clarify what the option does.I've heard a few folks say that it stops SQL Server from updating the statistics at the time of a rebuild; that isNOT what it does. Statistics are ALWAYS updated at the time of a REBUILD; this cannot be turned off (norwould you want to).

Instead, STATISTICS_NORECOMPUTE stops the database-wide auto-updating (auto update statistics) fromupdating the specific statistics for an index (or column-level statistic) that was created (or rebuilt) with thisoption turned on. NOTE: STATISTICS_RECOMPUTE only works when creating or rebuilding an index. If youwant to stop the auto-updating of a column-level statistic you use NORECOMPUTE when creating thatparticular statistic.

The more difficult question is if/when this would make sense to turn off – for either an index or a column-levelstatistic. And, yes, there are some cases where this can be appropriate.

The case where it makes sense to be turned off is for tables that are large in size and have very skewed datadistribution. For example, the ratio of line items per sale might be very evenly distributed between 1 and 3 itemswith an average of 2.1. Evenly distributed data tends to be easier to represent in a histogram (one of the piecesof information maintained in a statistic in SQL Server). However, sales per customer or sales per product mightbe much more uneven (and therefore skewed). And, when data distribution is skewed then then statistics arepotentially less accurate in a histogram. This is further exacerbated by the process that SQL Server maychoose of sampling your data. SQL Server will choose to sample your data (rather than reading every row)when the data they have to scan (ideally, an index but sometimes the table itself) is over 2,000 pages in size.

When would you know it’s a problem? If you run a query and you evaluate the estimated rows vs. the actual rows and the estimate seems significantlydifferent from the actual, then you might have a statistics problem. If you update statistics with the followingcode:

UPDATE STATISTICS tablename indexname (or statisticsname)

Then, try the query again. If this solved the problem, then you know that you’re not updating statistics enough. Ifit does not solve the problem then try updating the statistics will a fullscan:

UPDATE STATISTICS tablename indexname WITH FULLSCAN

If the estimate and actuals are more accurate (and typically result in better plans) then you might want to turnoff the auto-updating of the statistic and solely control this particular statistics update with a job that updates thestatistic with a full scan. The positive is that your statistics are likely to be more accurate and then your planswill be as well. The negative is that updating a statistic with a full scan can be a more costly maintenanceoperation. And, you have to be especially careful that your automated process doesn’t get removed or deletedleaving this statistic to never get auto-updated again.

In summary, I don’t often recommend STATISTICS_NORECOMPUTE on indexes (or NORECOMPUTE onstatistics) but there are cases when you might be able to better control the updating of statistics as well as allowfor a FULLSCAN. In these cases (and when you’re certain that your automated routines will not be interrupted/deleted/modified), then using this option can be beneficial!

QUESTION 6Your company has a SQL Azure subscription.

You implement a database named Database1. In Database1, you create two tables named Table1 and Table2.

You create a stored procedure named sp1. Sp1 reads data from Table1 and inserts data into Table2.

A user named User1 informs you that he is unable to run sp1. You verify that User1 has the SELECTpermission on Table1 and Table2. You need to ensure that User1 can run sp1. The solution must minimize thenumber of permissions assigned to User1. What should you do?

A. Grant User1 the INSERT permission on Table2.B. Add User1 to the db_datawriter role.C. Grant User1 the EXECUTE permission on sp1.D. Change sp1 to run as the sa user.


Explanation/Reference:According to this reference, the answer looks correct.


whilst the owner of the stored proc and the table are the same, then it would be sufficient to grant execute onthe stored procedure to do the insert unless the stored proc contains dynamic sql

See Ownership Chains

When multiple database objects access each other sequentially, the sequence is known as a chain. Althoughsuch chains do not independently exist, when SQL Server traverses the links in a chain, SQL Server evaluatespermissions on the constituent objects differently than it would if it were accessing the objects separately.These differences have important implications for managing security.Ownership chaining enables managing access to multiple objects, such as multiple tables, by settingpermissions on one object, such as a view. Ownership chaining also offers a slight performance advantage inscenarios that allow for skipping permission checks.How Permissions Are Checked in a ChainWhen an object is accessed through a chain, SQL Server first compares the owner of the object to the owner ofthe calling object. This is the previous link in the chain. If both objects have the same owner, permissions onthe referenced object are not evaluated.Example of Ownership ChainingIn the following illustration, the July2003 view is owned by Mary. She has granted to Alex permissions on theview. He has no other permissions on database objects in this instance. What occurs when Alex selects theview?

1. Alex executes SELECT * on the July2003 view. SQL Server checks permissions on the view and confirmsthat Alex has permission to select on it.

2. The July2003 view requires information from the SalesXZ view. SQL Server checks the ownership of theSalesXZ view. Because this view has the same owner (Mary) as the view that calls it, permissions onSalesXZ are not checked. The required information is returned.

3. The SalesXZ view requires information from the InvoicesXZ view. SQL Server checks the ownership of theInvoicesXZ view. Because this view has the same owner as the previous object, permissions on InvoicesXZare not checked. The required information is returned. To this point, all items in the sequence have had oneowner (Mary). This is known as an unbroken ownership chain.

4. The InvoicesXZ view requires information from the AcctAgeXZ view. SQL Server checks the ownership ofthe AcctAgeXZ view. Because the owner of this view differs from the owner of the previous object (Sam, notMary), full information about permissions on this view is retrieved. If the AcctAgeXZ view has permissionsthat enable access by Alex, information will be returned.

5. The AcctAgeXZ view requires information from the ExpenseXZ table. SQL Server checks the ownership ofthe ExpenseXZ table. Because the owner of this table differs from the owner of the previous object (Joe, notSam), full information about permissions on this table is retrieved. If the ExpenseXZ table has permissionsthat enable access by Alex, information is returned.

6. When the July2003 view tries to retrieve information from the ProjectionsXZ table, the server first checks tosee whether cross-database chaining is enabled between Database 1 and Database 2. If cross-databasechaining is enabled, the server will check the ownership of the ProjectionsXZ table. Because this table hasthe same owner as the calling view (Mary), permissions on this table are not checked. The requestedinformation is returned.

Cross-Database Ownership ChainingSQL Server can be configured to allow ownership chaining between specific databases or across all databasesinside a single instance of SQL Server. Cross-database ownership chaining is disabled by default, and shouldnot be enabled unless it is specifically required.Potential Threats

Ownership chaining is very useful in managing permissions on a database, but it does assume that objectowners anticipate the full consequences of every decision to grant permission on a securable. In the previousillustration, Mary owns most of the underlying objects of the July 2003 view. Because Mary has the right tomake objects that she owns accessible to any other user, SQL Server behaves as though whenever Marygrants access to the first view in a chain, she has made a conscious decision to share the views and table itreferences. In real life, this might not be a valid assumption. Production databases are far more complex thanthe one in the illustration, and the permissions that regulate access to them rarely map perfectly to theadministrative structures of the organizations that use them.

You should understand that members of highly privileged database roles can use cross-database ownershipchaining to access objects in databases external to their own. For example, if cross-database ownershipchaining is enabled between database A and database B, a member of the db_owner fixed database role ofeither database can spoof her way into the other database. The process is simple: Diane (a member ofdb_owner in database A) creates user Stuart in database A. Stuart already exists as a user in database B.Diane then creates an object (owned by Stuart) in database A that calls any object owned by Stuart in databaseB. Because the calling and called objects have a common owner, permissions on the object in database B willnot be checked when Diane accesses it through the object she has created.

QUESTION 7You are creating a database that will store usernames and passwords for an application. You need torecommend a solution to store the passwords in the database. What should you recommend? More than oneanswer choice may achieve the goal. Select the BEST answer.


A. Encrypting File System (EFS)B. One-way encryptionC. Reversible encryptionD. Transparent Data Encryption (TDE)



Reference:http://stackoverflow.com/questions/2329582/what-is-currently-the-most-secure-one-way-encryption-algorithmhttp://msdn.microsoft.com/en-us/library/ms179331.aspx

The concept of One way encryption is to encrypt the content and store it inside the database.If a person logs in with their authentication details the password would be encrypted and would be checkedagainst the encrypted value stored in the table. The hitch is if the user forgets their password it can't beretreived back. The only way out is the password needs to be reset.

Passwords should be hashed rather than encrypted as you simply need to check the hashes of a passwordrather than see what the password is.

QUESTION 8You are designing a SQL Server database for an order fulfillment system. You create a table namedSales.Orders by using the following script:

Each order is tracked by using one of the following statuses:FulfilledShippedOrderedReceived

A. To the Sales.Orders table, add a column named Status that will store the order status. Update the Statuscolumn as the order status changes.

B. To the Sales.Orders table, add three columns named FulfilledDate, ShippedDate, and ReceivedDate.Update the value of each column from null to the appropriate date as the order status changes.

C. Implement change data capture on the Sales.Orders table.D. Create a new table named Sales.OrderStatus that contains three columns named OrderID, StatusDate, and

Status. Insert new rows into the table as the order status changes.

QUESTION 20You have a SQL Server 2012 database named DB1. You have a backup device named Device1. You discoverthat the log file for the database is full. You need to ensure that DB1 can complete transactions. The solutionmust not affect the chain of log sequence numbers (LSNs). Which code segment should you execute?

A. BACKUP LOG DB1 TO Device1 WITH TRUNCATE_ONLY

B. BACKUP LOG DB1 TO Device1 WITH COPY_ONLY

C. BACKUP LOG DB1 TO Device1 WITH NORECOVERY

D. BACKUP LOG DB1 TO Device1



References:http://msdn.microsoft.com/en-us/library/ms186865.aspxhttp://msdn.microsoft.com/en-us/library/ms179478.aspxhttp://msdn.microsoft.com/en-us/library/ms190925.aspx

BACKUP LOG DB1 TO Device1One of the simplest ways to truncate the log is to perform a normal log backup:BACKUP LOG AdventureWorks TO DISK = 'c:\backups\advw20120317.trn'This will not break the LSN chain, and will effectively truncate the inactive portion of the log, IF a checkpoint hasbeen performed since the last log backup.Backing up the log in order to truncate it will not reduce the size of the physical log file, it will only clear inactivetransactions, thus preventing further unnecessary growth of the log file.

BACKUP LOG DB1 TO Device1 WITH COPY_ONLYSpecifies that the backup is a copy-only backup, which does not affect the normal sequence of backups. Acopy-only backup is created independently of your regularly scheduled, conventional backups. A copy-onlybackup does not affect your overall backup and restore procedures for the database.Copy-only backups were introduced in SQL Server 2005 for use in situations in which a backup is taken for aspecial purpose, such as backing up the log before an online file restore. Typically, a copy-only log backup isused once and then deleted.When used with BACKUP DATABASE, the COPY_ONLY option creates a full backup that cannot serve as adifferential base. The differential bitmap is not updated, and differential backups behave as if the copy-onlybackup does not exist. Subsequent differential backups use the most recent conventional full backup as theirbase.ImportantIf DIFFERENTIAL and COPY_ONLY are used together, COPY_ONLY is ignored, and a differential backup iscreated.When used with BACKUP LOG, the COPY_ONLY option creates a copy-only log backup, which does nottruncate the transaction log. The copy-only log backup has no effect on the log chain, and other log backupsbehave as if the copy-only backup does not exist.

BACKUP LOG DB1 TO Device1 WITH TRUNCATE_ONLYAn older method of truncating the log was to use BACKUP LOG WITH TRUNCATE_ONLY or BACKUP LOGWITH NO_LOG. These methods have been deprecated in SQL Server 2005, and were completely removedfrom SQL Server 2008 – and for good reason.

QUESTION 1Case Study 7: Invoice Schema ScenarioApplication InformationYour company receives invoices in XML format from customers. Currently, the invoices are stored as files andprocessed by a desktop application. The application has several performance and security issues. Theapplication is being migrated to a SQL Server-based solution. A schema named InvoiceSchema has beencreated for the invoices xml. The data in the invoices is sometimes incomplete. The incomplete data must bestored and processed as-is. Users cannot filter the data provided through views. You are designing a SQLServer database named DB1 that will be used to receive, process, and securely store the invoice data. A third-party Microsoft .NET Framework component will be purchased to perform tax calculations. The third-party taxcomponent will be provided as a DLL file named Treytax.dll and a source code file named Amortize.cs. Thecomponent will expose a class named TreyResearch and a method named Amortize(). The files are located inc:\temp\.

The following graphic shows the planned tables:

You have a sequence named Accounting.InvoiceID_Seq. You plan to create two certificates named CERT1and CERT2. You will create CERT1 in master. You will create CERT2 in DB1.

DatabasesEach office contains databases named Sales, Inventory, Customers, Products, Personnel, and Dev. Serversand databases are managed by a team of database administrators. Currently, all of the databaseadministrators have the same level of permissions on all of the servers and all of the databases. TheCustomers database contains two tables named Customers and Classifications. The following graphic showsthe relevant portions of the tables:

The following table shows the current data in the Classifications table:

The Inventory database is used mainly for reports. The database is recreated every day. A full backup of thedatabase currently takes three hours to complete.

Stored ProceduresA stored procedure named sp1 generates millions of rows of data for multiple reports. Sp1 combines data fromfive different tables from the Sales and Customers databases in a table named Table1. After Table1 is created,the reporting process reads data from a table in the Products database and searches for information in Table1based on input from the Products table. After the process is complete, Table1 is deleted. A stored procedurenamed sp2 is used to generate a product list. Sp2 takes several minutes to run due to locks on the tables theprocedure accesses. A stored procedure named sp3 is used to update prices. Sp3 is composed of severalUPDATE statements called in sequence from within a transaction. Currently, if one of the UPDATE statementsfails, the stored procedure continues to execute. A stored procedure named sp4 calls stored procedures in theSales, Customers, and Inventory databases. The nested stored procedures read tables from the Sales,Customers, and Inventory databases. Sp4 uses an EXECUTE AS clause. A stored procedure named sp5changes data in multiple databases. Security checks are performed each time sp5 accesses a database. Yoususpect that the security checks are slowing down the performance of sp5. All stored procedures accessed byuser applications call nested stored procedures. The nested stored procedures are never called directly.

Design RequirementsData RecoveryYou must be able to recover data from the Inventory database if a storage failure occurs. You have a RecoveryPoint Objective (RPO) of one hour. You must be able to recover data from the Dev database if data is lost

accidentally. You have a Recovery Point Objective (RPO) of one day.

Classification ChangesYou plan to change the way customers are classified. The new classifications will have four levels based on thenumber of orders. Classifications may be removed or added in the future. Management requests that historicaldata be maintained for the previous classifications.

SecurityA group of junior database administrators must be able to view the server state of the SQL Server instance thathosts the Sales database. The junior database administrators will not have any other administrative rights.------------QuestionYou need to recommend a solution for the planned changes to the customer classifications. What should yourecommend? (Each correct answer presents part of the solution. Choose all that apply.)

A. Add a table to track any changes made to the classification of each customer.B. Add columns for each classification to the Customers table.C. Implement change data capture.D. Add a row to the Customers table each time a classification changes.E. Add a column to the Classifications table to track the status of each classification.

QUESTION 1Case Study 2: Contoso LtdOverviewApplication OverviewContoso, Ltd., is the developer of an enterprise resource planning (ERP) application. Contoso is designing anew version of the ERP application. The previous version of the ERP application used SQL Server 2008 R2.The new version will use SQL Server 2012. The ERP application relies on an import process to load supplierdata. The import process updates thousands of rows simultaneously, requires exclusive access to thedatabase, and runs daily. You receive several support calls reporting unexpected behavior in the ERPapplication. After analyzing the calls, you conclude that users made changes directly to the tables in thedatabase.

TablesThe current database schema contains a table named OrderDetails. The OrderDetails table containsinformation about the items sold for each purchase order. OrderDetails stores the product ID, quantities, anddiscounts applied to each product in a purchase order. The product price is stored in a table named Products.The Products table was defined by using the SQL_Latin1_General_CP1_CI_AS collation. A column namedProductName was created by using the varchar data type. The database contains a table named Orders.Orders contains all of the purchase orders from the last 12 months. Purchase orders that are older than 12months are stored in a table named OrdersOld. The previous version of the ERP application relied on table-level security.

Stored ProceduresThe current version of the database contains stored procedures that change two tables. The following showsthe relevant portions of the two stored procedures:

Customer ProblemsInstallation IssuesThe current version of the ERP application requires that several SQL Server logins be set up to functioncorrectly. Most customers set up the ERP application in multiple locations and must create logins multipletimes.

Index Fragmentation IssuesCustomers discover that clustered indexes often are fragmented. To resolve this issue, the customersdefragment the indexes more frequently. All of the tables affected by fragmentation have the following columnsthat are used as the clustered index key:

Backup IssuesCustomers who have large amounts of historical purchase order data report that backup time is unacceptable.

Search IssuesUsers report that when they search product names, the search results exclude product names that containaccents, unless the search string includes the accent.

Missing Data IssuesCustomers report that when they make a price change in the Products table, they cannot retrieve the price thatthe item was sold for in previous orders.

Query Performance IssuesCustomers report that query performance degrades very quickly. Additionally, the customers report that userscannot run queries when SQL Server runs maintenance tasks.

Import IssuesDuring the monthly import process, database administrators receive many supports call from users who reportthat they cannot access the supplier data. The database administrators want to reduce the amount of timerequired to import the data.

Design RequirementsFile Storage RequirementsThe ERP database stores scanned documents that are larger than 2 MB. These files must only be accessedthrough the ERP application. File access must have the best possible read and write performance.

Data Recovery RequirementsIf the import process fails, the database must be returned to its prior state immediately.

Security RequirementsYou must provide users with the ability to execute functions within the ERP application, without having directaccess to the underlying tables.

Concurrency RequirementsYou must reduce the likelihood of deadlocks occurring when Sales.Proc1 and Sales.Proc2 execute.------------QuestionYou need to recommend a solution that addresses the concurrency requirement. What should yourecommend?

A. Make calls to Sales.Proc1 and Sales.Proc2 synchronously.B. Modify the stored procedures to update tables in the same order for all of the stored procedures.C. Call the stored procedures in a Distributed Transaction Coordinator (DTC) transaction.D. Break each stored procedure into two separate procedures, one that changes Sales.Table1 and one that

changes Sales.Table2.



According to these references, this answer looks correct.

EXAM ALL

QUESTION 1You have an application that uses a view to access data from multiple tables. You need to ensure that you caninsert rows into the underlying tables by using the view. What should you do?

A. Materialize the view.B. Create an INSTEAD OF trigger on the view.C. Define the view by using the CHECK option.D. Define the view by using the SCHEMABINDING option.


Explanation/Reference:References:http://msdn.microsoft.com/en-us/library/ms180800.aspxhttp://msdn.microsoft.com/en-us/library/ms187956.aspx

You can modify the data of an underlying base table through a view, as long as the following conditions aretrue:

Any modifications, including UPDATE, INSERT, and DELETE statements, must reference columns fromonly one base table.The columns being modified in the view must directly reference the underlying data in the table columns.The columns cannot be derived in any other way, such as through the following:

1. An aggregate function: AVG, COUNT, SUM, MIN, MAX, GROUPING, STDEV, STDEVP, VAR, and VARP.2. A computation. The column cannot be computed from an expression that uses other columns. Columns that

are formed by using the set operators UNION, UNION ALL, CROSSJOIN, EXCEPT, and INTERSECTamount to a computation and are also not updatable.The columns being modified are not affected by GROUP BY, HAVING, or DISTINCT clauses.TOP is not used anywhere in the select_statement of the view together with the WITH CHECK OPTIONclause.

Materialize the view.In SQL this is an indexed view

CHECK OPTIONForces all data modification statements executed against the view to follow the criteria set withinselect_statement. When a row is modified through a view, the WITH CHECK OPTION makes sure the dataremains visible through the view after the modification is committed. Any updates performed directly to a view'sunderlying tables are not verified against the view, even if CHECK OPTION is specified.

SCHEMABINDINGBinds the view to the schema of the underlying table or tables. When SCHEMABINDING is specified, the basetable or tables cannot be modified in a way that would affect the view definition. The view definition itself mustfirst be modified or dropped to remove dependencies on the table that is to be modified. When you useSCHEMABINDING, the select_statement must include the two-part names (schema.object) of tables, views, oruser-defined functions that are referenced. All referenced objects must be in the same database.Views or tables that participate in a view created with the SCHEMABINDING clause cannot be dropped unlessthat view is dropped or changed so that it no longer has schema binding. Otherwise, the Database Engineraises an error. Also, executing ALTER TABLE statements on tables that participate in views that have schemabinding fail when these statements affect the view definition.

If the previous restrictions prevent you from modifying data directly through a view, consider the followingoptions:INSTEAD OF Triggers

INSTEAD OF triggers can be created on a view to make a view updatable. The INSTEAD OF trigger isexecuted instead of the data modification statement on which the trigger is defined. This trigger lets the userspecify the set of actions that must happen to process the data modification statement. Therefore, if anINSTEAD OF trigger exists for a view on a specific data modification statement (INSERT, UPDATE, orDELETE), the corresponding view is updatable through that statement. For more information about INSTEADOF triggers, see DML Triggers.Partitioned ViewsIf the view is a partitioned view, the view is updatable, subject to certain restrictions. When it is needed, theDatabase Engine distinguishes local partitioned views as the views in which all participating tables and the vieware on the same instance of SQL Server, and distributed partitioned views as the views in which at least one ofthe tables in the view resides on a different or remote server.

Conditions for Modifying Data in Partitioned ViewsThe following restrictions apply to statements that modify data in partitioned views:The INSERT statement must supply values for all the columns in the view, even if the underlying membertables have a DEFAULT constraint for those columns or if they allow for null values. For those member tablecolumns that have DEFAULT definitions, the statements cannot explicitly use the keyword DEFAULT.The value being inserted into the partitioning column should satisfy at least one of the underlying constraints;otherwise, the insert action will fail with a constraint violation.UPDATE statements cannot specify the DEFAULT keyword as a value in the SET clause, even if the columnhas a DEFAULT value defined in the corresponding member table.Columns in the view that are an identity column in one or more of the member tables cannot be modified byusing an INSERT or UPDATE statement.If one of the member tables contains a timestamp column, the data cannot be modified by using an INSERT orUPDATE statement.If one of the member tables contains a trigger or an ON UPDATE CASCADE/SET NULL/SET DEFAULT or ONDELETE CASCADE/SET NULL/SET DEFAULT constraint, the view cannot be modified.INSERT, UPDATE, and DELETE actions against a partitioned view are not allowed if there is a self-join with thesame view or with any of the member tables in the statement.Bulk importing data into a partitioned view is unsupported by bcp or the BULK INSERT and INSERT ... SELECT* FROM OPENROWSET(BULK...) statements. However, you can insert multiple rows into a partitioned view byusing the INSERT statement.NoteTo update a partitioned view, the user must have INSERT, UPDATE, and DELETE permissions on the membertables.

QUESTION 2You create a view by using the following code:

Several months after you create the view, users report that the view has started to return unexpected results.You discover that the design of Table2 was modified since you created the view. You need to ensure that theview returns the correct results. Which code segment should you run?

A. EXEC sp_refreshview @viewname = 'dbo.View1';

B. ALTER dbo.View1 WITH SCHEMABINDING, VIEW_METADATAASSELECT t1.col1, t1.col2, t2.*FROM dbo.Table1 AS t1 JOIN dbo.Table2 AS t2ON t1.col1 = t2.col2;

C. DROP dbo.View1;GO

CREATE dbo.View1 WITH SCHEMABINDING, VIEW_METADATAAS SELECT t1.col1, t1.col2, t2.*FROM dbo.Table1 AS t1 JOIN dbo.Table2 AS t2ON t1.col1 = t2.col2;

D. EXEC sp_refreshsqlmodule @name = 'dbo.Table2';


Explanation/Reference:References:http://msdn.microsoft.com/en-us/library/ms173846.aspxhttp://msdn.microsoft.com/en-us/library/ms187956.aspxhttp://msdn.microsoft.com/en-us/library/ms187821.aspxhttp://msdn.microsoft.com/en-us/library/bb326754.aspx

sp_refreshviewIf a view is not created with schemabinding, sp_refreshview should be run when changes are made to theobjects underlying the view that affect the definition of the view. Otherwise, the view might produce unexpectedresults when it is queried.

sp_refreshsqlmoduleUpdates the metadata for the specified non-schema-bound stored procedure, user-defined function, view, DMLtrigger, database-level DDL trigger, or server-level DDL trigger in the current database. Persistent metadata forthese objects, such as data types of parameters, can become outdated because of changes to their underlyingobjects.

sp_refreshsqlmodule should be run when changes are made to the objects underlying the module that affect itsdefinition. Otherwise, the module might produce unexpected results when it is queried or invoked. To refresh aview, you can use either sp_refreshsqlmodule or sp_refreshview with the same results.

ALTER ViewModifies a previously created view. This includes an indexed view. ALTER VIEW does not affect dependentstored procedures or triggers and does not change permissions.

SCHEMABINDINGBinds the view to the schema of the underlying table or tables. When SCHEMABINDING is specified, the basetables cannot be modified in a way that would affect the view definition. The view definition itself must first bemodified or dropped to remove dependencies on the table to be modified. When you use SCHEMABINDING,the select_statement must include the two-part names (schema.object) of tables, views, or user-definedfunctions that are referenced. All referenced objects must be in the same database.Views or tables that participate in a view created with the SCHEMABINDING clause cannot be dropped, unlessthat view is dropped or changed so that it no longer has schema binding. Otherwise, the Database Engineraises an error. Also, executing ALTER TABLE statements on tables that participate in views that have schemabinding fail if these statements affect the view definition.VIEW_METADATASpecifies that the instance of SQL Server will return to the DB-Library, ODBC, and OLE DB APIs the metadatainformation about the view, instead of the base table or tables, when browse-mode metadata is beingrequested for a query that references the view. Browse-mode metadata is additional metadata that the instanceof Database Engine returns to the client-side DB-Library, ODBC, and OLE DB APIs. This metadata enables theclient-side APIs to implement updatable client-side cursors. Browse-mode metadata includes information aboutthe base table that the columns in the result set belong to.For views created with VIEW_METADATA, the browse-mode metadata returns the view name and not thebase table names when it describes columns from the view in the result set.When a view is created by using WITH VIEW_METADATA, all its columns, except a timestamp column, areupdatable if the view has INSERT or UPDATE INSTEAD OF triggers. For more information, see the Remarkssection in CREATE VIEW (Transact-SQL).

QUESTION 4You have an index for a table in a SQL Azure database. The database is used for Online TransactionProcessing (OLTP). You discover that the index consumes more physical disk space than necessary. You needto minimize the amount of disk space that the index consumes. What should you set from the index options?

A. STATISTICS_NORECOMPUTE = OFFB. STATISTICS_NORECOMPUTE = ONC. FILLFACTOR = 0


D. FILLFACTOR = 80



Reference: http://msdn.microsoft.com/en-us/library/ms177459.aspxhttp://msdn.microsoft.com/en-us/library/ms188783.aspx

FILLFACTOR

This topic describes what fill factor is and how to specify a fill factor value on an index in SQL Server 2012 byusing SQL Server Management Studio or Transact-SQL.The fill-factor option is provided for fine-tuning index data storage and performance. When an index is createdor rebuilt, the fill-factor value determines the percentage of space on each leaf-level page to be filled with data,reserving the remainder on each page as free space for future growth. For example, specifying a fill-factorvalue of 80 means that 20 percent of each leaf-level page will be left empty, providing space for indexexpansion as data is added to the underlying table. The empty space is reserved between the index rows ratherthan at the end of the index.The fill-factor value is a percentage from 1 to 100, and the server-wide default is 0 which means that theleaf-level pages are filled to capacity.Performance ConsiderationsPage SplitsA correctly chosen fill-factor value can reduce potential page splits by providing enough space for indexexpansion as data is added to the underlying table.When a new row is added to a full index page, the DatabaseEngine moves approximately half the rows to a new page to make room for the new row. This reorganization isknown as a page split. A page split makes room for new records, but can take time to perform and is aresource intensive operation. Also, it can cause fragmentation that causes increased I/O operations. Whenfrequent page splits occur, the index can be rebuilt by using a new or existing fill-factor value to redistribute thedata. For more information, see Reorganize and Rebuild Indexes.Although a low, nonzero fill-factor value may reduce the requirement to split pages as the index grows, theindex will require more storage space and can decrease read performance. Even for an application oriented formany insert and update operations, the number of database reads typically outnumber database writes by afactor of 5 to 10. Therefore, specifying a fill factor other than the default can decrease database readperformance by an amount inversely proportional to the fill-factor setting. For example, a fill-factor value of 50can cause database read performance to decrease by two times. Read performance is decreased because theindex contains more pages, therefore increasing the disk IO operations required to retrieve the data.Adding Data to the End of the TableA nonzero fill factor other than 0 or 100 can be good for performance if the new data is evenly distributedthroughout the table. However, if all the data is added to the end of the table, the empty space in the indexpages will not be filled. For example, if the index key column is an IDENTITY column, the key for new rows isalways increasing and the index rows are logically added to the end of the index. If existing rows will be updatedwith data that lengthens the size of the rows, use a fill factor of less than 100. The extra bytes on each page willhelp to minimize page splits caused by extra length in the rows.

STATISTICS_NORECOMPUTEQuestion: Recently I noticed an option with CREATE/ALTER INDEX called STATISTICS_NORECOMPUTE?I'm not sure I understand this option or why you'd ever want to use it? Can you explain?

Answer: In general, I don't recommend this option. But, before I get to why - let me clarify what the option does.I've heard a few folks say that it stops SQL Server from updating the statistics at the time of a rebuild; that isNOT what it does. Statistics are ALWAYS updated at the time of a REBUILD; this cannot be turned off (norwould you want to).

Instead, STATISTICS_NORECOMPUTE stops the database-wide auto-updating (auto update statistics) fromupdating the specific statistics for an index (or column-level statistic) that was created (or rebuilt) with thisoption turned on. NOTE: STATISTICS_RECOMPUTE only works when creating or rebuilding an index. If youwant to stop the auto-updating of a column-level statistic you use NORECOMPUTE when creating thatparticular statistic.

The more difficult question is if/when this would make sense to turn off – for either an index or a column-levelstatistic. And, yes, there are some cases where this can be appropriate.

The case where it makes sense to be turned off is for tables that are large in size and have very skewed datadistribution. For example, the ratio of line items per sale might be very evenly distributed between 1 and 3 itemswith an average of 2.1. Evenly distributed data tends to be easier to represent in a histogram (one of the piecesof information maintained in a statistic in SQL Server). However, sales per customer or sales per product mightbe much more uneven (and therefore skewed). And, when data distribution is skewed then then statistics arepotentially less accurate in a histogram. This is further exacerbated by the process that SQL Server maychoose of sampling your data. SQL Server will choose to sample your data (rather than reading every row)when the data they have to scan (ideally, an index but sometimes the table itself) is over 2,000 pages in size.

When would you know it’s a problem? If you run a query and you evaluate the estimated rows vs. the actual rows and the estimate seems significantlydifferent from the actual, then you might have a statistics problem. If you update statistics with the followingcode:

UPDATE STATISTICS tablename indexname (or statisticsname)

Then, try the query again. If this solved the problem, then you know that you’re not updating statistics enough. Ifit does not solve the problem then try updating the statistics will a fullscan:

UPDATE STATISTICS tablename indexname WITH FULLSCAN

If the estimate and actuals are more accurate (and typically result in better plans) then you might want to turnoff the auto-updating of the statistic and solely control this particular statistics update with a job that updates thestatistic with a full scan. The positive is that your statistics are likely to be more accurate and then your planswill be as well. The negative is that updating a statistic with a full scan can be a more costly maintenanceoperation. And, you have to be especially careful that your automated process doesn’t get removed or deletedleaving this statistic to never get auto-updated again.

In summary, I don’t often recommend STATISTICS_NORECOMPUTE on indexes (or NORECOMPUTE onstatistics) but there are cases when you might be able to better control the updating of statistics as well as allowfor a FULLSCAN. In these cases (and when you’re certain that your automated routines will not be interrupted/deleted/modified), then using this option can be beneficial!

QUESTION 6Your company has a SQL Azure subscription.

You implement a database named Database1. In Database1, you create two tables named Table1 and Table2.

You create a stored procedure named sp1. Sp1 reads data from Table1 and inserts data into Table2.

A user named User1 informs you that he is unable to run sp1. You verify that User1 has the SELECTpermission on Table1 and Table2. You need to ensure that User1 can run sp1. The solution must minimize thenumber of permissions assigned to User1. What should you do?

A. Grant User1 the INSERT permission on Table2.B. Add User1 to the db_datawriter role.C. Grant User1 the EXECUTE permission on sp1.D. Change sp1 to run as the sa user.




whilst the owner of the stored proc and the table are the same, then it would be sufficient to grant execute onthe stored procedure to do the insert unless the stored proc contains dynamic sql

See Ownership Chains

When multiple database objects access each other sequentially, the sequence is known as a chain. Althoughsuch chains do not independently exist, when SQL Server traverses the links in a chain, SQL Server evaluatespermissions on the constituent objects differently than it would if it were accessing the objects separately.These differences have important implications for managing security.Ownership chaining enables managing access to multiple objects, such as multiple tables, by settingpermissions on one object, such as a view. Ownership chaining also offers a slight performance advantage inscenarios that allow for skipping permission checks.How Permissions Are Checked in a ChainWhen an object is accessed through a chain, SQL Server first compares the owner of the object to the owner ofthe calling object. This is the previous link in the chain. If both objects have the same owner, permissions onthe referenced object are not evaluated.Example of Ownership ChainingIn the following illustration, the July2003 view is owned by Mary. She has granted to Alex permissions on theview. He has no other permissions on database objects in this instance. What occurs when Alex selects theview?

1. Alex executes SELECT * on the July2003 view. SQL Server checks permissions on the view and confirmsthat Alex has permission to select on it.

2. The July2003 view requires information from the SalesXZ view. SQL Server checks the ownership of theSalesXZ view. Because this view has the same owner (Mary) as the view that calls it, permissions onSalesXZ are not checked. The required information is returned.

3. The SalesXZ view requires information from the InvoicesXZ view. SQL Server checks the ownership of theInvoicesXZ view. Because this view has the same owner as the previous object, permissions on InvoicesXZare not checked. The required information is returned. To this point, all items in the sequence have had oneowner (Mary). This is known as an unbroken ownership chain.

4. The InvoicesXZ view requires information from the AcctAgeXZ view. SQL Server checks the ownership ofthe AcctAgeXZ view. Because the owner of this view differs from the owner of the previous object (Sam, notMary), full information about permissions on this view is retrieved. If the AcctAgeXZ view has permissionsthat enable access by Alex, information will be returned.

5. The AcctAgeXZ view requires information from the ExpenseXZ table. SQL Server checks the ownership ofthe ExpenseXZ table. Because the owner of this table differs from the owner of the previous object (Joe, notSam), full information about permissions on this table is retrieved. If the ExpenseXZ table has permissionsthat enable access by Alex, information is returned.

6. When the July2003 view tries to retrieve information from the ProjectionsXZ table, the server first checks tosee whether cross-database chaining is enabled between Database 1 and Database 2. If cross-databasechaining is enabled, the server will check the ownership of the ProjectionsXZ table. Because this table hasthe same owner as the calling view (Mary), permissions on this table are not checked. The requestedinformation is returned.

Cross-Database Ownership ChainingSQL Server can be configured to allow ownership chaining between specific databases or across all databasesinside a single instance of SQL Server. Cross-database ownership chaining is disabled by default, and shouldnot be enabled unless it is specifically required.Potential Threats

Ownership chaining is very useful in managing permissions on a database, but it does assume that objectowners anticipate the full consequences of every decision to grant permission on a securable. In the previousillustration, Mary owns most of the underlying objects of the July 2003 view. Because Mary has the right tomake objects that she owns accessible to any other user, SQL Server behaves as though whenever Marygrants access to the first view in a chain, she has made a conscious decision to share the views and table itreferences. In real life, this might not be a valid assumption. Production databases are far more complex thanthe one in the illustration, and the permissions that regulate access to them rarely map perfectly to theadministrative structures of the organizations that use them.

You should understand that members of highly privileged database roles can use cross-database ownershipchaining to access objects in databases external to their own. For example, if cross-database ownershipchaining is enabled between database A and database B, a member of the db_owner fixed database role ofeither database can spoof her way into the other database. The process is simple: Diane (a member ofdb_owner in database A) creates user Stuart in database A. Stuart already exists as a user in database B.Diane then creates an object (owned by Stuart) in database A that calls any object owned by Stuart in databaseB. Because the calling and called objects have a common owner, permissions on the object in database B willnot be checked when Diane accesses it through the object she has created.

QUESTION 7You are creating a database that will store usernames and passwords for an application. You need torecommend a solution to store the passwords in the database. What should you recommend? More than oneanswer choice may achieve the goal. Select the BEST answer.

A. Encrypting File System (EFS)B. One-way encryptionC. Reversible encryptionD. Transparent Data Encryption (TDE)



Reference:http://stackoverflow.com/questions/2329582/what-is-currently-the-most-secure-one-way-encryption-algorithmhttp://msdn.microsoft.com/en-us/library/ms179331.aspx

The concept of One way encryption is to encrypt the content and store it inside the database.If a person logs in with their authentication details the password would be encrypted and would be checkedagainst the encrypted value stored in the table. The hitch is if the user forgets their password it can't beretreived back. The only way out is the password needs to be reset.

Passwords should be hashed rather than encrypted as you simply need to check the hashes of a passwordrather than see what the password is.

QUESTION 20You have a SQL Server 2012 database named DB1. You have a backup device named Device1. You discoverthat the log file for the database is full. You need to ensure that DB1 can complete transactions. The solutionmust not affect the chain of log sequence numbers (LSNs). Which code segment should you execute?

A. BACKUP LOG DB1 TO Device1 WITH TRUNCATE_ONLY

B. BACKUP LOG DB1 TO Device1 WITH COPY_ONLY

C. BACKUP LOG DB1 TO Device1 WITH NORECOVERY

D. BACKUP LOG DB1 TO Device1




BACKUP LOG DB1 TO Device1One of the simplest ways to truncate the log is to perform a normal log backup:BACKUP LOG AdventureWorks TO DISK = 'c:\backups\advw20120317.trn'This will not break the LSN chain, and will effectively truncate the inactive portion of the log, IF a checkpoint hasbeen performed since the last log backup.Backing up the log in order to truncate it will not reduce the size of the physical log file, it will only clear inactivetransactions, thus preventing further unnecessary growth of the log file.

BACKUP LOG DB1 TO Device1 WITH COPY_ONLYSpecifies that the backup is a copy-only backup, which does not affect the normal sequence of backups. Acopy-only backup is created independently of your regularly scheduled, conventional backups. A copy-onlybackup does not affect your overall backup and restore procedures for the database.Copy-only backups were introduced in SQL Server 2005 for use in situations in which a backup is taken for aspecial purpose, such as backing up the log before an online file restore. Typically, a copy-only log backup isused once and then deleted.When used with BACKUP DATABASE, the COPY_ONLY option creates a full backup that cannot serve as adifferential base. The differential bitmap is not updated, and differential backups behave as if the copy-onlybackup does not exist. Subsequent differential backups use the most recent conventional full backup as their

base.ImportantIf DIFFERENTIAL and COPY_ONLY are used together, COPY_ONLY is ignored, and a differential backup iscreated.When used with BACKUP LOG, the COPY_ONLY option creates a copy-only log backup, which does nottruncate the transaction log. The copy-only log backup has no effect on the log chain, and other log backupsbehave as if the copy-only backup does not exist.

BACKUP LOG DB1 TO Device1 WITH TRUNCATE_ONLYAn older method of truncating the log was to use BACKUP LOG WITH TRUNCATE_ONLY or BACKUP LOGWITH NO_LOG. These methods have been deprecated in SQL Server 2005, and were completely removedfrom SQL Server 2008 – and for good reason.

------------QuestionYou need to build a stored procedure that amortizes the invoice amount. Which code segment should you useto create the stored procedure? To answer, move the appropriate code segments from the list of codesegments to the answer area and arrange them in the correct order.


Correct Answer:





DatabasesEach office contains databases named Sales, Inventory, Customers, Products, Personnel, and Dev. Serversand databases are managed by a team of database administrators. Currently, all of the databaseadministrators have the same level of permissions on all of the servers and all of the databases. TheCustomers database contains two tables named Customers and Classifications. The following graphic shows

the relevant portions of the tables:






SecurityA group of junior database administrators must be able to view the server state of the SQL Server instance thathosts the Sales database. The junior database administrators will not have any other administrative rights.------------QuestionYou need to recommend a solution for the planned changes to the customer classifications. What should yourecommend? (Each correct answer presents part of the solution. Choose all that apply.)

A. Add a table to track any changes made to the classification of each customer.B. Add columns for each classification to the Customers table.C. Implement change data capture.D. Add a row to the Customers table each time a classification changes.E. Add a column to the Classifications table to track the status of each classification.



Reference:http://msdn.microsoft.com/en-us/library/cc645937.aspx





Stored ProceduresA stored procedure named sp1 generates millions of rows of data for multiple reports. Sp1 combines data fromfive different tables from the Sales and Customers databases in a table named Table1. After Table1 is created,

the reporting process reads data from a table in the Products database and searches for information in Table1based on input from the Products table. After the process is complete, Table1 is deleted. A stored procedurenamed sp2 is used to generate a product list. Sp2 takes several minutes to run due to locks on the tables theprocedure accesses. A stored procedure named sp3 is used to update prices. Sp3 is composed of severalUPDATE statements called in sequence from within a transaction. Currently, if one of the UPDATE statementsfails, the stored procedure continues to execute. A stored procedure named sp4 calls stored procedures in theSales, Customers, and Inventory databases. The nested stored procedures read tables from the Sales,Customers, and Inventory databases. Sp4 uses an EXECUTE AS clause. A stored procedure named sp5changes data in multiple databases. Security checks are performed each time sp5 accesses a database. Yoususpect that the security checks are slowing down the performance of sp5. All stored procedures accessed byuser applications call nested stored procedures. The nested stored procedures are never called directly.



SecurityA group of junior database administrators must be able to view the server state of the SQL Server instance thathosts the Sales database. The junior database administrators will not have any other administrative rights.------------QuestionYou need to recommend a change to sp3 to ensure that the procedure completes only if all of the UPDATEstatements complete. Which change should you recommend?

A. Set the IMPLICIT_TRANSACTIONS option to off.B. Set the XACT_ABORT option to offC. Set the IMPLICIT_TRANSACTIONS option to on.D. Set the XACT_ABORT option to on.

TablesThe current database schema contains a table named OrderDetails. The OrderDetails table containsinformation about the items sold for each purchase order. OrderDetails stores the product ID, quantities, anddiscounts applied to each product in a purchase order. The product price is stored in a table named Products.

The Products table was defined by using the SQL_Latin1_General_CP1_CI_AS collation. A column namedProductName was created by using the varchar data type. The database contains a table named Orders.Orders contains all of the purchase orders from the last 12 months. Purchase orders that are older than 12months are stored in a table named OrdersOld.
