Uhmmm, I think I didn't make myself clear. What I mean by void function
wasn't a function which just doesn't return anything. What I meant is a
function created like this:
create function voidfunction returns *void* as [...]
The problem to me is the void in the returns ;)
If you create a function with the returns void above you'll see that if
you do select * from voidfunction it gives you the error I said. But it
works with select voidfunction.
I just wanted it to work with select * from voidfunction too. :)
Thanks Nigel.
