And 'exists' is not for mysqldump.
DROP TABLE IF EXISTS mytable;
"if exists" can be used in lots of places other than "drop table", like triggers, functions and i'm sure other things.
I said, I've seen EXIST in a result of a mysqldump before, which is not wrong is it? Unless I'm hallucinating... Or is EXISTS something completely different?
Yes it is completely different.
