But it doesn't. In SQL, NULL + 3 is NULL In Perl, undef + 3 is 3. There's nothing quite like the "stickiness" of NULL in SQL. It's important not to say they're equivalent without also pointing out how different they are. That's the problem I had with the casual answers in the rest of the thread. -- Randal L.
