It's good - and it's "free",
By A Customer
This review is from: MySQL Certification Study Guide (Paperback)
I've read the first couple of chapters, and can only say: Paul DuBois (and his co-authors Stefan Hinz and Carsten Pedersen who, for some reason, aren't listed as authors on Amazon) have done it again: Written an excellent book on MySQL. I have yet to go and actually sit the exam, but I think that this book will have me well prepared by the time I go.
I find it frustrating that there are no "real" sample questions -- almost all exercises are open-ended, but what you'll see on the exam are multiple-choice questions. That's why I'm not giving the book the 5 stars that the main text deserves.
Oh, and the book is free -- that is, if you're certain you're going to go to the exam anyway. There's a discount voucher inside the book that'll be good for $50.00 (the list price of the book) off of an exam...
