MySQL 4.1 Core Certification

I passed the MySQL 4.1 Core certification this morning. I’ve been using MySQL 3.23.x and some of the 4.x releases for about five years now. I thought I’d breeze through the test a bit quicker. The questions were mostly well written and experience appropriate to a test of this level. My only complaints are questions that use absolutes like “all” or “none”, and then don’t provide full and thorough answers to choose from. Thankfully these were few and tended to be applied to the more fluff questions.
The thing that surprised me most was the number of questions on
subqueries. These are new to 4.1 and in the past you’ve always been encouraged to rewrite subqueries as a join. I guess MySQL really has decided to fully embrace subqueries.
