Create if an entry doesn't exist, otherwise update?

Question

Kinda strange to put it into words that short, heh.

Anyway, what I want is basically to update an entry in a table if it does exist, otherwise to create a new one fillin

As the others have said, REPLACE is the way to go. Just be careful using it though, since it actually does a DELETE and INSERT on the table. This is fine most of the time, but if you have foreign keys with constraints like ON DELETE CASCADE, it can cause some big problems.
