Re: stored procedure(?) question

You could build a UDTF wrapper around the rpg program

select * from tablelist where invno in (select invbvr from table (myudtf())
as X);

Take a look at this Redbook, "External Procedures, Triggers, and
User-Defined Functions on IBM DB2 for i"
https://www.redbooks.ibm.com/abstracts/sg246503.html?Open

And even better, an article from Scott..

Hi Vern,

the list is generated from files on the iseries. I am using an RPG
program to create the "list". Its basically 1 field that contains a list
of invoice number. So after my rpg program is done, the list might look
like:

INV1
INV2
INV5
INV15

i would like to take the results of this and us them in an sql like:

select claims from claimtable where invoicenbr in (inv1,inv2,inv5,in15).

Does that make any sense?

Hi Tim

The list has to be in a data file of some kind - if it's in QTEMP or
wherever, you can use it.

What kind of thing is the list? It could be an array, content in a
user space, whatever. Let us know, we can help better, then.

I have an rpg program that generates a list of invoices (not using
sql to create list). I would like to use this generated list in sql.

so,

select * from tablelist where invno in (rpg program generated list)

is this possible?
