AH-HA
I'm making some headway
using
CREATE FUNCTION AVAILQTY (VARCHAR(4), VARCHAR(6))
RETURNS DECIMAL(9,0)
LANGUAGE RPGLE
PARAMETER STYLE GENERAL
EXTERNAL NAME 'PRODLIB/SERVPGM(SUBPROC)'
DETERMINISTIC
NO SQL
NOT FENCED
RETURNS NULL ON NULL INPUT

I do get some results
for example
ITEM SKUNO AVAIL
NO.
SUFFIX
0011 000070 999,999,999-

where the answer 999,999,999- is a valid answer when the item is NOT
found on the item master
Even though I can see its there.
Trying to use debug does not get me into the service program

BUT - I'm making headway

Thanks to everyone who came up with suggestions

Maybe create your function using VARCHAR instead of CHAR - or
explicitly CAST the values in your SELECT to be CHAR values.

Thanks for your reply Birgitta
Unfortunately I still got the same response

ITEM SKUNO AVAIL

SUFFIX

Hi,

I assume it's the parameter style.
Parameter style expects some additional (optional) parameters that
must
be
defined in the procedure interface or *ENTRY PLIST.
Try to recreate your function with parameter style general. With
parameter
style general only the defined parameters are passed to the RPG
function.

Overloading cannot be the problem, because the function gets called.
If a function is overloaded and the parameters are not passed with
the
same
data types (BTW length must not be an exact match, because it's not
checked), the function gets not called at all. Be careful CHAR and
VARCHAR
are different data types. SMALLINT, INT and BIGINT are also 3
different
data
types.

Mit freundlichen Grüßen / Best regards

Betreff: Creating an SQL function

Good morning all
I am trying to create an SQL function that uses a sub procedure
within a
service program
Here is what I attempted
Within STRSQL

create function MYLIB/AVAILQTY (CHAR, CHAR)
returns DECIMAL(9,0)
External Name 'PRODLIB/SERVPGM(SUBPROC)'
Language RPGLE
Disallow Parallel
No SQL
Parameter Style DB2SQL
Deterministic

When I attempt to use this, for example
SELECT SUFFIX, SKUNO, AVAILQTY(SUFFIX, SKUNO)
FROM ITEMMSTR WHERE SUFFIX = '0011' AND SKUNO = '000070'

What I get is
ITEM SKUNO AVAILQTY
NO.
SUFFIX
0011 000070 ++++++++++++
The input to the sub procedure is 2 fields 4 characters, 6 characters
The output from the sub procedure is decimal(9,0) as noted above
I'll be honest
I don't know where to start on debugging this
If anyone can help, it would be much appreciated)


Thanks in advance
