Re: Execute immediate problem

When I asked someone in the know about big VARCHAR2 variables, they mentioned declaring VARCHAR2(32500). Don't know if there's a reason for going less than 32767 (overhead stored along with the variable?) but you might try using a somewhat smaller length.

BTW, declaring a big VARCHAR2 like this is also a good way to avoid exceptions when concatenating values where you don't know the length of the final result. Above a certain limit (about 4K), PL/SQL only allocates as much memory as needed, rather than the full declared length of the variable. So it's slightly slower but doesn't waste any memory.
