Re: Returning result set from external stored procedure

Alan

I'm halfway between you and Scott - heh - I actually constructed a copy member with conditional includes based on release - can't publish it, since it's for our products.

And a person CAN use the base ODBC functions on a PC - even with VB - guess I'm fairly comfortable with APIs, whether in Windows and VB or in OS/400 and RPG.

Glutton for punishment!

I don't know if I would agree with that Scott.

The SQL CLI interface was designed for C programmers and requires a translation
of the C type variables to RPG type variables and knowledge of calling System
API's. Not trivial knowledge.

In other languages, using ODBC interfaces is pretty simple and there are a
million examples floating around.

Not so in the AS/400 world. In the AS/400 world calling procedures is a big
deal. In the VB or other worlds it is just part of the gig. Most people couldn't
imagine doing it any other way.

Also most PC languages have wrappers that hide most of the complexity. You just
use those API's instead of programming directly to the ODBC API which is what
SQL CLI is.

I don't know if anyone has written a service program wrapper for the SQL CLI
functions. Don't know how often it would get used. Would be an interesting
project.

Anyway, my opinion only.

Hi Vern,

The only way now to use a stored procedure in an RPG program is to
use SQL/CLI - the call level interface - not necessarily for the
faint of heart, although I do use it in some of our stuff.

Heh... it's not "the only way". There are other ways! You could call
JDBC instead of CLI. Or you could launch the db2 QShell command via the
spawn() API, and read back it's results, etc.

CLI is just the "easiest" way, and performs the best.

I find it interesting that you say it's not for the feint-of-heart, yet,
CLI is the programming interface of ODBC, and is "the standard" for
writing apps that do database access! It goes to show how spoiled we
are in RPG, where embedded SQL is easy, and record-level I/O is easy.
Other languages all use CLI, or something very much like it (like JDBC)
any time they do database access.
