I was considering getting a study guide to help with the mysql certification exam. At first I see one for what seems to be mysql 4+. AN older version that rates highly on amazon.
However, I later found on another site the mysql 5 certification book. Now, do you feel it is best to just learn mysql 5 and study that? Or would my 4+ knowledge be acceptable in today's world? I don't use mysql 5 and have no idea what the differences are.
