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
