I write bigger C library - implementation of some dbms_packages and plvision packages. I don't expect using plpgsql. I have a lot of void functions. Usually set_...unset_ with and I need sql language for createing wrappers for default values. That's all. Second. The logic in PostgreSQL is wrong now. Is too hard and too simple. I can get VOID value via SELECT void function too.

Let's imagine you want to do (roughly) the equivalent of CALL, which we don't have yet. This would let you have what amounts to a stored procedure, i.e. something that takes an action but doesn't return rows. :) Cheers, D -- David Fetter <[EMAIL PROTECTED]> http://fetter.org/ phone: +1 415 235 3778AIM: dfetter666 Skype: davidfetter Remember to vote! ---(end of broadcast)--- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
