I find it a lot easier to code SQL functions in SQL. No need for RPG. If
you have to, the SQL code can call an RPG program .

then use SPECIFIC to assign the name of the service program the system
creates for the sql function. That makes it relatively easy to debug using
STRDBG.

here is a sample SQL function:

CREATE OR REPLACE FUNCTION dwhpf30c_isDropShip(
inCucode char(6),
inOrdnum decimal(9,0))
RETURNS char(1)
language sql
SPECIFIC DWHPF30CFB
SET OPTION DATFMT = *ISO, DLYPRP = *YES, DBGVIEW = *SOURCE,
USRPRF = *OWNER, DYNUSRPRF = *OWNER, COMMIT = *CHG
BEGIN

DECLARE VMSG CHAR(80) ;
DECLARE VCMDSTR CHAR(256) ;
declare vCount int default 0 ;

select count(*)
into vCount
from dwhpf30d a
where a.ordcust = inCucode and a.ordordnum = inOrdnum
and a.ordwhc = 'PNY'
fetch first row only ;
if vCount > 0 then
return 'Y' ;
else
return 'N' ;
end if ;

END

I have a program that takes a manifest# and a pick ticket# and returns a

with that info.

I found some info on the great rpgpgm.com, so I wrote my UDF wrapper.
My Full code here, https://code.midrange.com/9430223040.html,

Snip here
dcl-proc GetPPKQty export ;
dcl-pi GetPPKQty int(5);
ppManifest zoned(8) const ;
ppInvoice char(16) const;
end-pi ;
dcl-s outPcs int(5) ;

My SQL Create
CREATE OR REPLACE FUNCTION WHSLIB.WHSO643R (ppManifest
DECIMAL(8,0),ppInvoice Char(16))
RETURNS INT
LANGUAGE RPGLE
DETERMINISTIC
NO SQL
EXTERNAL NAME 'WHSLIB/WHSO643R(GETPPKQTY)'
PARAMETER STYLE GENERAL
PROGRAM TYPE SUB ;


When I try to run my SQL update I get a decimal error.

select sdinvoice, sdmanif#, sdqty, whso643r(sdmanif#,sdinvoice)
from xxxr021

I tried to STRDBG on the UDF but that I get Pointer not set for location
referenced.
