RE: %parms() BIF

You can keep them as the same name... with one passing a parm and the other
not passing the parm. Then SQL will determine with one to use.

Well that just sucks.......

Ok, in order to make the procedures more intuitive, I just separated
them into two separate procedures. getCashByAcct, and getCashAllAccts.

Thanks,

Mark,

SQL doesn't pass a basic operational descriptor, unlike RPG. It is
this opdesc which lets the RPG subprocedure know how many parameters
have been passed. The same goes for some other languages (no doubt
someone else will chime in which ones they are, if you're interested...).

Anyway, to solve your probelm, the easiest thing to do is to add
code to your RPG sub-procedure to treat blank parameters as
equivalent to un-passed parameters, and then pass those parameters
as blank from the SQL function.

I have a sub-procedure in a service program that uses the %parms()

I call it from an SQL External function, it returns -1. Any idea why?

Thanks,
