SQL Server Compact

• Very small (~2 MB) embedded, in-proc database• Nice subset of SQL Server types and SQL dialect• Enables embedded, private, non-admin deployment

What it is

• Mobile, embedded devices, desktop, starter websites• Windows Vista/7, Media Center PC, MSN Client,

ZUNE, Windows Media Player, …• Default local/client database offering in VS 2010

Where it’s deployed

• Local online / offline cache• Local, stand alone application database• Persistent data manager for in-memory database• Structured document format for custom apps

Scenarios

User Code within the Database Stored Procs User Defined Functions

CLR within the database Out of proc

If the hosting app isn’t running, the database isn’t running Out of proc achieved through developer defined Windows Service

Multiple User Roles Application will manage security rights to the database

SQL Server Compact and ASP.NET

• Server Explorer• Query Designer• Transact-SQL Editor

Stand-alone designers (not tied to any project)

• Dataset Configuration, Entity Framework• Web Forms• Drag and drop of SQL Compact tables on Web Forms

Project based code generating designers

• Click Once• Web (MS) deployApplication deployment designers

• Project upgrade ,and add new or an existing Local Database• New item template for Compact in Web projects• Add SDF file in App_Data

Other project based miscellaneous designers

• Paid VS SKUs: Pro, Premium, Ultimate• Free: C# Express, VB Express and Visual Web Developer ExpressVS SKU support

Tooling in Visual Studio

DEMO: ASP.NET and SQL Server Compact 4.0

SqlCeConnectionString… File path Specifies password And options e.g. Encryption Mode, Max Database Size, Mode(R/W), Autoshrink

Use |DataDirectory| macro To resolve obfuscated .SDF database file location

Use “Max database size” for larger databases Defaults to 128MB for devices and 256 MB for desktop

SQL Server Compact

Accessing Data

Change Managed Provider reference to Copy Local = true

Include both 32 and 64 bit Compact engine DLLs Place 32bit version under an X86 Place 64bit version under AMD64

AMD64 includes Intel X64 Folder Name based off:

Copy the DLLs from the private folder

SQL Server Compact

Deployment

Environment.GetEnvironmentVariable("PROCESSOR_ARCHITECTURE")

It’s free, fast, safe/encryptable and compact It’s easy to program and manage Single file, code free, doc centric file format It’s an alternative to JET, XML persisted DataSets, SQL Server Express It’s integrated into:

Visual Studio 2010 WebMatrix Beta

It provides for seamless migration of schema and data to SQL Server
