Did you set and return SQLSTATE 02000 after having read and returned the
last row?

Betreff: Simple UDTF only gets called with OPEN, FETCH events
I'm trying out user defined table functions based on Scott Klement's example
at
http://www.scottklement.com/presentations/RPG%20User%20Defined%20Functions%2
0%26%20Table%20Functions.pdf
My code is at
http://code.midrange.com/399002eaaa.htm.
The interesting thing is that my UDTF only gets called with a call type of
-1 (open) and 0 (fetch), but never 1 (close).
I tried creating the function without the NO FINAL CALL, which theoretically
means my UDTF should have been called with a call type of
-2 (startup) and 2 (final) as well as the open/fetch/close, but still only
got called on open and fetch. I have a counter that's incremented each time
the function is called, and put in DSPLYs like this
0045.00 dsply ('STARTUP: ' + %editc(CallType:'L') + ' ' + SQLSTT
+ ' '
0046.00 + %editc(Counter:'L') + ' '
0047.00 + %editc(parmIn:'L'));
to see what was happening and ran it from the green screen STRSQL just to
keep it simple and this is what I got:
STRSQL
select * from table(UDTF1(1)) as t
SELECT statement run complete.
DSPLY OPEN...: 1- 00000 1 1
DSPLY FETCH..: 0 00000 2 1
DSPLY FETCH..: 0 00000 3 1
DSPLY FETCH..: 0 00000 4 1
DSPLY FETCH..: 0 00000 5 1
DSPLY FETCH..: 0 00000 6 1
DSPLY FETCH..: 0 02000 7 1
....+...
PARMOUT
2
3
4
5
******** End of data ********
STRSQL
select * from table(UDTF1(2)) as t
SELECT statement run complete.
DSPLY OPEN...: 1- 00000 8 2
DSPLY FETCH..: 0 00000 9 2
DSPLY FETCH..: 0 02000 10 2
....+...
PARMOUT
******** End of data ********
STRSQL
select * from table(UDTF1(3)) as t
SELECT statement run complete.
DSPLY OPEN...: 1- 00000 11 3
DSPLY FETCH..: 0 00000 12 3
DSPLY FETCH..: 0 02000 13 3
....+...
PARMOUT
******** End of data ********
DSPLY OPEN...: 1- 00000 14 4
DSPLY FETCH..: 0 00000 15 4
DSPLY FETCH..: 0 02000 16 4
....+...
PARMOUT
******** End of data ********
Anyone have an idea what's going on? Is it because I'm calling it from
STRSQL? It occurred to me that maybe the close and final calls happen when I
sign off, so I did a SIGNOFF *LIST, but the resulting job log did not show
anything after the last FETCH.
