Use of Temporary Data Set
With Summary (Item, Created) as
(Select ilitm, MIN(JDDCONV(iltrdj)) as Created
from fotedta.F4111 Where ildct = 'IC'
group by ilitm) Select imlitm, imdsc1, created from
fotedta.F4101 Join Summary on imitm = item

Here is a simple determination of the first time an item in our inventory was created. The first ‘IC’ record for a product in the Inventory Transaction file can be pulled by applying the “MIN” function to the transaction date. The “With” operation permits the building of a temporary data set to be used for joining to another file and helping to limit or enhance the data being presented.

Many times I will use the Interactive STRSQL to build and test the concepts. After I have the desired results I can take the statement and copy/paste into the Excel Addin, the Client Access Data Transfer From IBM i, or a 3rd party product such as Linoma’s Surveyor.
Here is a statement to determine the number of Purchase Orders our customers in Canada have been send us by month for the past two years.
The qualified Files and Functions (QGPL.JDDCONV) are required when running in a client program that probably doesn’t have a full Library List. I add then to the statement prior to copying it to the clipboard.
Open Excel and select Transfer Data from IBM I
Enter Library and File name to continue. Library and File must exist but probably do not have to be the primary file of the SQL.
Select Properties and on Conversions Tab select Convert CCSID 65535.On SQL Tab change from Data Transfer to native SQL.Use OK.
Then select Data Options (this window will validate the Library & File in the earlier panel).
In the SQL Select statement window, highlight the existing statement and then paste the copied statement in the window. The statement can be modified if necessary.
Select OK and then next panel will have option to run.
Results in Excel
In Client Access select Transfer Data from IBM i.
Select the Properties icon and there will be the same screens for the transfer as in Excel.Then Ok and then select Data Options.
The same Change SQL Select Options panel will be presented and can be copy/paste the same as in Excel.
Upon return to the transfer panel the PC options will permit extract to Display, HTML, Printer, or File in various formats.
Routine to Advance Date to End of Month
SELECT Jddconv(MFDRQJ) as DATE, ((Jddconv(MFDRQJ) + 1 Month) - 1 Day) as
NEWDATE, MFDRQJ as JDEJulian, Cast(('1' ||
Substr(Digits(Year((Jddconv(MFDRQJ) + 1 Month) - 1 Day)),9,2) ||

- 1 Day)),8,3)) as Dec(6,0)) as NEWJUL From F3460 Where Day(Jddconv(MFDRQJ)) = '01'
This routine will set a date that is the 1st day of the month to the last day of the month. e. g. 01/01/13 to 01/31/13 Add 1 to the current month and then subtract 1 day. ps. The newjul field in the select takes a " MMDDYY" date field to JDE Julian. Each of the result fields of the Digits operands are 10 digit results. Digits(year(date)) = 0000002013 needs substr(result,9,2) for 13 or substr(result,7,4) for 2013.

Remove Duplicate Records
• Select iesku, Count(*) From itemex Group By iesku Having Count(*) > 1
• Select RRN(a) as RRNO, iesku From itemex a Where Exists (Select * From qtemp/dupitems b Where b.iesku = a.iesku
• Select iesku, Max(RRNO) as maxrrno From qtemp/dupitems2 Group By iesku
• Delete From itemex b Where RRN(b) In (Select maxrrno From qtemp/dupitems3)
1. Output a list of SKUs that have more than record to a work file. (qtemp/DUPITEMS)
2. Output list of relative record numbers of SKUs that are in the list of duplicate items. (qtemp/DUPITEMS2)
3. Output a list of the highest relative (Last) record numbers from the list of relative record numbers for each SKU. (qtemp/DUPITEMS3)
4. Delete any record whose relative record number is in the list of the highest relative record number for a SKU.
5. Rinse, repeat till all duplicates are deleted. (looking at the counts in the first file will show the number of times the process will need to be repeated)
Note: More than a couple of fields to determine duplicate records will make the first select statement unwieldy as all fields will have to be repeated in each select
Excerpt from ITJungle Four Hundred Guru – Three Powerful SQL Words Published
December 4, 2013 by Ted HoltConsider the following summary query:• select d.ItemNumber, sum(d.Quantity) as Qty, sum(d.Quantity * d.Price) as
Extended from InvoiceLines as d group by d.ItemNumber order by 1Here's the result set:• ITEMNUMBER QTY EXTENDED• A-1 8 88.00 • A-3 7 35.00 • A-7 7 52.00 • B-1 26 51.25 • Z-3 2 18.00Standard stuff, yet very powerful. It beats writing an RPG program to read a file,
check for a control break on item number, sum the quantity and extended price, and write the results to some device. Unquestionably, SQL is powerful.
Would you like SQL to be a little more powerful? (The correct answer is "Yes!") Look at this query. Notice the next-to-last line, in red.
• select d.ItemNumber, sum(d.Quantity) as Qty, sum(d.Quantity * d.Price) as Extended from InvoiceLines as d group by d.ItemNumber with rollup order by 1
And here's the result set. Look at the last line.• ITEMNUMBER QTY EXTENDED • A-1 8 88.00 • A-3 7 35.00 • A-7 7 52.00 • B-1 26 51.25 • Z-3 2 18.00 • - 50 244.25Those two powerful words, WITH ROLLUP, were enough to sum up the item
groups into grand totals.Notice the first column of the last row. The summary row for all items cannot
have an item number, so the item number column is null.
Remaining two words:Group By with Rollup
And Grouping• GROUP BY builds summary totals by item within
date. WITH ROLLUP builds date totals and grand totals. Notice the nulls in the rows that were built by the rollup.
• Today's third powerful word is GROUPING. This powerful function accepts a column name and returns 0 or 1 to indicate whether or not WITH ROLLUP generated a summary row over that column. I think of the zero as false and the 1 as true, even though SQL has no Boolean type.
