The example I gave was overly simplistic. I actually want to look at more than one of the columns in the returned
record,so rewritting it to return an int won't address the need for the other columns. And no, it does not return a
set/arrayof records. It returns just one record.
If I run the function outside of a query, it returns something like...
"(myvcharval1,myvcharval2,myintval)"
Notice the parens, the commas and the lack of single quotes around the "myvcharval(x)" values.
I suppose I could do some funky string dissection with this, but I was wondering if there was something more
straignt-forward.

I think, you should rewrite your function to hand over the id_num as
additional parameter. But i'm not sure if i understand you corrently. Is
this a setof-returning function?
Please, show us your real function, maybe someone can help you more.
