SQL UDF problem

Hi group,

Yesterday evening we migrated (finally) from our V5R3 system to a brand new enterprise system at V7R1.

All seemed well until I tried to use a UDF in SQL this morning. It takes in a date in numeric ISO format, and should return a date in excel format (# of days since 01/01/1900).

However, it always returns zero.

I re-created the function using the following syntax:

create function colpaerp.isotoexcel(decimal(8, 0))
returns numeric(8, 0)
external name 'SRVPGMLIB/SQLUDF(ISOTOEXCEL)'
language rpgle
parameter style db2sql
no sql
deterministic
no external action
returns null on null input
allow parallel;

This is the source of the function in the service program:

P IsoToexcel b Export
d IsoToExcel pi 8s 0
d IsoDate 8p 0 const

D Xls_StartDate S D inz(d'1900-01-01')
D retVal s 8s 0 inz
/free
Reset retVal;
test(de) *iso IsoDate;
If %error;
Else;
If IsoDate > *zeros;
retVal = %diff(%date(IsoDate:*iso):xls_startdate:*d) + 2;
EndIf;
Endif;

Return %dec(retVal:10:0);

/end-free
p IsoToExcel e

When I debugged the function, the retVal contained the correct value, but in the SQL result it was zero.

Is there a difference between V5R3 and V7R1 when creating the function?

FWIW, the V5 system was first restored on a new V6 system, which was subsequently upgraded to V7.

Any help would be greatly appreciated.

Met vriendelijke groeten / Best regards,
