Hi Walter,

A little more information might help:

STRSQL

select substr(SPECIFIC_SCHEMA,1,20) slib,
substr(SPECIFIC_NAME,1,20) sname,
substr(ROUTINE_SCHEMA,1,20) rlib,
substr(ROUTINE_NAME,1,20) rname,
EXTERNAL_NAME
from QSYS2/SYSFUNCS
where lower(ROUTINE_NAME) = 'idate'

Or just leave off the WHERE clause and take a look at all the functions on your system. If you see idate in there, and the EXTERNAL_NAME is correct, expand the SELECT to show all fields, i.e. SELECT * FROM QSYS2/SYSFUNCS and look at some of the other information, like the PARAMETER_STYLE and so on to make sure it matches what you expect; or what Alan says it should show.

Walter, try doing s WRKOBJ OBJ(*ALLUSR/XVIDAT) OBJTYPE(*SRVPGM)

See if there are multiple copies of XVIDAT around.

Hi Vernon,

We're on V6.1. I'm attempting to debug the iDate UDF that Alan
Campin has so kindly shared. I'm just running a simple select
statement from a STRSQL. I've attempted these two scenarios:

I've tried it with BREAK as follows:

- Session 1: STRSRVJOB JOB(123456/MYUSERID/SESSION2)
- Session 1: STRDBG UPDPROD(*YES) SRVPGM(QGPL/XVIDAT)
- Session 1: BREAK on the first statement of each procedure in both
modules XVIDAT_M01 and XVIDAT_M02.
- Session 2: STRSQL
- Session 2: select idate(someDateField) from someTable

Dates are shown edited, but none of the breakpoints occur.


I also tried it with SBREAK as Alan had suggested as follows and
also no
luck:

- Session 1: STRDBG UPDPROD(*YES) SRVPGM(QGPL/XVIDAT)
- Session 1: "sbreak LINE# user MYUSERID" on the first statement of
each procedure in both modules XVIDAT_M01 and XVIDAT_M02.
- Session 2: STRSQL
- Session 2: select idate(someDateField) from someTable

Alan states: " It will break on your previous statement and tell you
the STRSRVJOB command to use on another session. Then issue STRDBG
in that session."

It did not break. I also tried substituting sbreak LINE# user
MYUSERID in the first scenario, and no luck.

Walter - if you're willing, tell us just what steps you took? What
release of the OS are you on? SBREAK would get you what you want,
but it is a relatively recent thing - v5r3 or v5r4.

If you used SBREAK, you have to set the user you want - that is
often QUSER for server jobs - so which user did you specify?

I forget now about UDFs, but I think SQL could be doing things in a
server job, not your own - again, you'd have a hard time figuring
which job to debug unless you can use SBREAK.

Hope to help!
Vern

Thanks for all of your responses. Still can't get a breakpoint to
come
up. I know the function is working because it is converting the
dates as described. In response to Peter, the service program only
exists in QGPL, and the CREATE FUNCTION qualifies the service
program. Was there a PTF that may have been needed?

I should clarify that more. In one session just do a STRDBG and
then
issue a SBREAK for the line you want to break and your user id. Then
in another session, run your SQL. It will break on your previous
statement and tell you the STRSRVJOB command to use on another
session. Then issue STRDBG in that session.

I'm attempting to debug a User Defined Function that uses a
service program to do the work on a V6.1 release. This is the
iDate source downloaded from A. Campin, with the modules, service
program and functions created properly. STRSRVJOB and STRDBG are
done on one session, and a simple STRSQL with a select statement
that uses the UDF is done on the other session that the STRSRVJOB
points to. A break point was set on the first statement of every
procedure in both modules and I can't get a module to stop at any of the break points.
The RPGLE modules of the service program were also compiled with
DBGVIEW(*ALL) and that did not work as well. Has anyone
encountered a
similar problem?
