Subject One SP that can return any kind of value?
Author
Hi all

I have a few SPs (see two examples below), I have a field that defines which field's value is to be returned but as the SP needs a RETURN specified to a type (that what I believe), I wrote separate SPs for each return type, but is it possible to have one SP and unknown RETURN value?

Please advise.

Thanks and regards
