RE: Stored Procedure: Default Values For Parameters

Not that I've seen, but you are free to implement your own procedure
overloading.

You could define 4 different procedure with the same name (i.e. MyProc),
each taking 0,1,2 and 3 parameters respectively. Versions with less than
'max' parameters would set default values for the non-specified parameters
and simply pass-thru to the 'max' version procedure.

Then when you call it at run-time, system would invoke the appropriate
procedure based on the signature used (i.e. 0,1,2 or 3 parms used). You
wouldn't care which one gets invoked as they all do the same thing.

Subject: Stored Procedure: Default Values For Parameters

Is there a way to declare default values for paramters in a procedures in
DB2/400?

I've looked high and low and I'm getting the impression there's not. Other
platforms will let you do something like:

CREATE PROCEDURE MyProc(
IN Param1 char(1)=' ',
IN Param2 money = 0,
IN Param3 varchar(50) = null)
etc.

CALL MyProc (Param1='Y');

Param1 will equal 'Y'. Param2 and Param3 are available within the procedure
as values 0 and NULL respectively. Does that situation exist in DB2/400?

Thanks
