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

Charles,

1) Thanks, lots to learn. If I understand what I think I know, the speed
difference between dynamic and static SQL is in the path analysis and
package preparation steps, the SQL statement runs at the same speed. For the
enhancements I plan to start with, that time penalty is not a big issue. If
we end up doing a significant rewrite on the system, I'll deal with it later
after I understand more.

2) Nawww, we don't use WDSCi/SEU. Notepad works just fine...

One thing to note is that performance of DYNSQL is going to be worse
than with actual embedded SQL.

Particularly when it come to static SQL statements, ie. the fields
returned and files access don't change each time the program is run.

So do you have to code with WDSCi/SEU to?

All,

 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.

Many thanks, JK
