AW: Debugging Remote Stored Procedure Calls

Hi,

if you want to register a RPG with optional parameters as stored procedures
and overload it, you need to define and check your optional parameters with
Options(*NOPASS: *OMIT). If a overloaded procedure (with optional
parameters) is called, for the not passed parameters a NULL Pointer is
passed, which must be checked as If %Addr(Parm) = *NULL. %Parms always
returns the number of all passed parameters (including NULL-Pointer, i.e.
*OMITTED)


Mit freundlichen Grüßen / Best regards

Betreff: Debugging Remote Stored Procedure Calls

All,

I have a conundrum that I can't decipher. I have a program that
contains optional parameters.

d*----------------------------------------------------------------------
--*
d* entry routine
d*----------------------------------------------------------------------
--*
d entry pi
d reqRefID$ 13a varying
d transID$ 13a options(*nopass) const varying
d begDate$ d options(*nopass) const
d endDate$ d options(*nopass) const

reqRefID$ is a return (output) variable in these calls.

If I make the calls from an RPG program, all is well. However, I have
three (3) variations of the call from SQL stored procedures, and only
one is working as expected.

Here are the procedures:

This one works as expected...
CREATE PROCEDURE MYLIB/MYPROCA (
OUT referenceID varchar(13),
IN orderID varchar(13))
EXTERNAL NAME MYLIB/MYPROC LANGUAGE RPGLE

This one returns the OUT variable, but does not produce any records...
CREATE PROCEDURE MYLIB/MYPROCB (
OUT referenceID varchar(13),
IN orderID varchar(13),
IN begDate date,
IN endDate date)
EXTERNAL NAME MYLIB/MYPROC LANGUAGE RPGLE

This one returns the OUT variable, but does not produce any records...
CREATE PROCEDURE MYLIB/MYPROCC (
OUT referenceID varchar(13))
EXTERNAL NAME MYLIB/MYPROC LANGUAGE RPGLE

This is the input logic:
/free
// get a unique key for the request
#get_unique('MYFIELD':k_field$:e_stat$:k_count$);
// if key returned, process request
if e_stat$ = 0;
// set return value
reqRefIDD$ = k_field$;
reqRefID$ = %char(%int(k_field$));
if %parms >= 2;
// select query type
monitor;
transIDD$ = %dec(transID$:13:0);
on-error;
transIDD$ = 0;
endmon;
if %parms >= 2 and transIDD$ > 0;
// get by trans id
exsr getTransID;
elseif %parms = 4 and begDate$ <= endDate$;
// get by date range
exsr getTransIDs;
endif;
else; // no optinal parms passed
exsr loopqueue;
endif;
endif;
// return unique key
*inlr = *on;
/end-free

These stored procedures are being called from ColdFusion on a remote
server.

Is there any way that I can invoke debugging during the remote call to
see what the program is receiving as input?

Thanks,
