Now as to ANSI, there is a standards compliance statement in each SQL Reference manual. Here it is for V5R3 & V5R2 (V5R1 had only the first 2):
ANSI (American National Standards Institute) X3.135-1992, Database Language SQL - Entry Level ANSI (American National Standards Institute) X3.135?4: 1996, Database Language SQL - Part 4: Persistent Stored Modules (SQL/PSM) ANSI (American National Standards Institute) X3.135-1999, Database Language SQL - Core
There is also the "SQL Reference for Cross-Platform Development" book at ftp://ftp.software.ibm.com/partnerworld/vic/hardware/pdfs/b4e.pdfthat has an appendix that lists terminology differences between ANSI and DB2 - this is a cross-platform DB2 manual, BTW. It does not go so far as to relate SQL terms to native iSeries terms, such as table to physical file, etc.
I highly recommend going to the site at http://www.iseries.ibm.com/db2 if you want to investigate things more thoroughly. There are comparisons within the DB2 family (iSeries seems to have almost everything that is in the list at V5R3) and lots of other stuff. Dig around.
Finally, I can recommend a nice basic tutorial at http://www.w3schools.com - I've been using it for Javascript information, but there are several other things there, including SQL. It reminds you, for one, that there is a "standard". But each vendor has their own extensions. But if you get through that tutorial (not hard, you can probably do it in 1-2 hours at most), you will have a very nice start. Then you need to learn just what the built-in functions are, what other statements there might be, etc., from the SQL Reference manual for iSeries.
I'll say what I always do - you don't need to know much - learn the basic structure of the SELECT statement and you are good to do for, I suppose, 90% of SQL work. The WHERE clause is used in DELETEs and UPDATES (and sometimes in INSERTs, within a SELECT that returns the rows to insert). In other words, SQL consists of using the same basic building blocks repeatedly.
At the above site there is also a tutorial on ADO - aimed at usage within ASP in web pages, but I'll bet the basics are there, very similar to what you'd do in any Visual Basic example. There's also one for .NET - both of these can be used against an iSeries database, so the generality and universality still comes into play.

Isn't IBM's implementation of SQL pretty much the ANSI standard? Reading a book for Oracle or SQLServer may lead you to try some of their proprietary extensions, which invariably leads to heads beating against walls. The references really aren't that bad, and the list is very helpful. Learn to write UDF's. Mike E.
