Query: Save your money

This book is supposed to cover Transact-SQL, an advanced topic. But it uses a database which you must type in! Although it includes a CD-ROM, the database is not on it. If I want a typing exercise, I'd buy Mavis Beacon's. Most of the first portion of the book covers basic SQL tools. A complete waste of time in an advanced text. Also, much of the text and many of the illustrations are based on a beta version of SQL 7, so they don't even apply to the version you'll see (for example, see pg. 40, which tells how to create a Database Diagram, and is COMPLETELY WRONG). The writing style is also unclear and difficult to follow. The only benefit I got from the book is the author's name - I've used it to start a list of authors I'll avoid at all cost in the future.
