Hi,
I have questions to udfs:

1. its possible to make a function that gets argument of any type
(varchar,timestamp,...) and in body find out what type is it?

This would mean you would be (needing to) pass a "variant" to a stored
procedure in the first place so I can't see that happening.

2. Can I find out that argument gived to the function is null?

IF :ARUMENT IS NULL THEN
would work
