1. DB2 SQL from the Trenches George Smith Metro Midrange Systems Association November 18, 2014

2. Use of Temporary Data Set With Summary (Item, Created) as (Select ilitm, MIN(JDDCONV(iltrdj)) as CreatedJDDCONV from fotedta.F4111 Where ildct = 'IC' group by ilitm) Select imlitm, imdsc1, created from fotedta.F4101 Join Summary on imitm = item Where imstkt = 'S' and created > '01/01/2011' Order by 3 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.

3. From a response in JDEList for the JDDCONV date conversion used my examples By using three SQL functions you can turn a JD Edwards Julian date into a more usable format. The following SQL statement will give you all of the sales order records from F4211 that have a transaction date greater than today's date: SELECT * FROM F4211 WHERE DATE(DIGITS(DECIMAL(SDTRDJ + 1900000,7,0))) > CURRENT DATE The DECIMAL(SDTRDJ + 1900000,7,0) will turn the internal date into a Julian format of YYYYNNN. The DIGITS function turns the numeric value into a character string. The DATE function will convert the character string into a date data type. The "CURRENT DATE" value will substitute today's date. To specify a date other than today use: SELECT * FROM F4211 WHERE DATE(DIGITS(DECIMAL(SDTRDJ + 1900000,7,0))) > '11/13/03‘ (Continued on next slide)

4. At my current client site I used the following to create a function called JDDCONV in library QGPL: CREATE FUNCTION QGPL/JDDCONV (JDEDATE DECIMAL(6,0)) RETURNS DATE LANGUAGE SQL SET OPTION DATFMT=*ISO BEGIN DECLARE F_OUTPUT DATE ; DECLARE F_TEST INTEGER ; DECLARE CONTINUE HANDLER FOR SQLEXCEPTION SET F_TEST = 1 ; SET F_TEST = 0; SET F_OUTPUT = DATE(DIGITS(DECIMAL(JDEDATE+1900000,7,0))); IF F_TEST = 0 THEN RETURN F_OUTPUT ; ELSE RETURN NULL; END IF; END I then can change my original SQL statement to: SELECT * FROM F4211 WHERE JDDCONV(SDTRDJ) > CURRENT DATE I hope this helps.

18. Using the SQL Statement in Excel Addin With Summary (sdan8, sdvr01, Month, Year, xxx) as (select sdan8, sdvr01, Trim(char(Month(qgpl.jddconv(sdtrdj)))) as Month, Trim(char(Year(qgpl.jddconv(sdtrdj)))) as Year, count(*) from fotedta.f42119 where trim(sdmcu) = '150' and sddcto in ('SO', 'SZ') and sdtrdj > 113000 and sdaddj <> 0 group by sdan8, sdvr01, Trim(char(Month(qgpl.jddconv(sdtrdj)))), Trim(char(Year(qgpl.jddconv(sdtrdj))))) Select Year, Case When Length(Month) = 1 Then '0' concat Month Else Month End as Month, sdan8, abalph, count(*) as #of_PO from summary join fotedta.f0101 on sdan8 = aban8 group by year, Case When Length(Month) = 1 Then '0' concat Month Else Month End, sdan8, abalph order by 1, 2, 3 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 3 rd 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.

19. 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.

20. Select Properties and on Conversions Tab select Convert CCSID 65535. On SQL Tab change from Data Transfer to native SQL. Use OK.

21. 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.

22. Results in Excel

23. 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.

24. 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.

25. 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) || Substr(Digits( DayOfYear((Jddconv(MFDRQJ) + 1 Month) - 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.

(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

29. Excerpt from ITJungle Four Hundred Guru – Three Powerful SQL Words Published December 4, 2013 by Ted Holt Consider 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 1 Here'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 18.00 Standard 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.

30. 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 - 50 244.25 Those 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.

31. 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.
