Query: A Big Disappointment

This book isn't what I thought it would be. I expected a tutorial that would spend more time on using PHP with a database. In reality it only has eight simple and not very useful examples. The remainder of the book is a reference section which consumes 445 of the 597 pages.And to top it off, the reference section has so many errors that you end up spending more time troubleshooting the book's errors than you do writing good code.
