SQL

Great Book
It is a great SQL Server programming reference book that gives you something beyond T-SQL programming.
There is a lot of material here and it's well laid out for both skimming as well as in depth reading.

Very good book about every detail of SQL Server 2008 that you would want to know and then some.
For the SQL Server Professional this book is a must have.
This book is excellent. I found it at Barnes and Noble, read at the store, decided to buy one.
This must be the first book you should read (page by page) if you are serious about being an expert on SQL Server administration and development.

SQL: The Complete Reference by James R. Groff and Paul N. Weinberg

This book lives up to its name, as it is truly a complete listing of all the concepts in SQL.
This a very easy book and the examples showed are very, very helpful.
The best bit about the book is that it is really written using Standard SQL (ANSI).
This is very big book and when you see it. The fact is that it is a big book because it is very complete and thorough.
This book served as an excellent learning tool, then later as an excellent reference.

Inside Microsoft® SQL Server® 2008: T-SQL Querying by Itzik Ben-Gan, Lubor Kollar, Dejan Sarka and Steve Kass

This book is a jewel. It gives complex and useful SQL algorithms along with explanation both on logic side and on performance side.
In general, this book is well written and conveys the material in logical and progressive order. But readers should be ready for a great deal of theory.
This book is superbly edited, and one hears the different voices of the authors, but there is a careful coordination of content.
This is a good book as a reference book for beginner to intermediate knowledge of SQL.

The book is very well-written and easy to follow compared to the few other books I've purchased on databases/sql so far.

This is the book. Written in a manner that is understandable yet thorough.
