Re: ISTKT & DYNSQL vs. 5722ST1 SQL Development Kit

IIRC, DYNSQL is a SRVPGM with embedded SQL, so I assume you have a compiled
object. If you want metadata on the result set (sort of SQL DESCRIBE), it
may let you down with calculated fields, as it uses the SYSCOLUMNS LF,
which will not return. The maximum number of cursors (or active SQL
statements) is 8. 

I have not used it, only looked at it many moons ago. I wrote my own
dynamic SQL utilty instead.

Other options:  
1) You can create QMQRY objects with SQL statements in a SRCPF and the
CRTQMQRY command. Then run the QMQRY with STRQMQRY. You can pass parameters
to the query for dynamic data selection. This can be wrapped in a CLP with
a command interface. 
2) You can use the QSQPRCED API. Midrange Computing had an interesting
article on it, search the website www.mcpressonline.com.

Our iSeries shop is small, with an even smaller software budget so

purchasing the IBM SQL precompiler (5722ST1) simply isn't going to happen.

We've muddled by with OPNQRYF and ASC's "Sequel" product (which is a great

tool) but without the ability to embed 'Select' statements into RPG or CL,

we've not been able to take full advantage of SQL.

Until yesterday, that is, when I girded my loins, plunged into that scary

SourceForge site, imported the "iSeries toolkit" and stayed up past

midnight playing with DYNSQL.

It appears that DYNSQL will enable me to build dynamic SQL statements,

declare cursors and fetch results directly into RPG and CL. What more could

a guy want? DYNSQL requires a slightly different syntax than IBM's

precompiler, but those are just technical details, right?

So I'd like to:
1) say thanks to David Morris and his compadres for making this available,

and

2) ask whether anyone else has used DYNSQL instead of IBM's offering and

what differences I should be aware of (other than syntax) between the two

products. The goal is not to chuck all the native I/O, but to enhance it

where the payback is greatest. Count(*) and Sum(amount) now become easy, as

well as dynamic sorting and filtering of subfiles.
