Easy to follow, well written book. Can easily be used in liue of a textbook. Get spiral edition.
Format: Spiral-bound
Walter Shields does a fantastic job of writing this book from a perspective that a reader will have no clue on databases, or SQL. I'm a former Database programmer, but after being away for so many years I had to come back to SQL, and I needed a reference quick. Everything is written in a step by step easy to swallow informational way that leaves no room for failure. Even the examples are fantastic. This book is compatible with opensource SQL so need to pay for anything but the book.
Get the spiral edition, it lays flat on the table and is easier to follow.
Unlike McGraw Hill, Cengage, Thomson Course Technology, this book doesn't expire and block you from buying a used copy to prevent you from downloading the files needed to learn.
A fantastic reference, a great book, timeless because it doesn't expire.

SQL qsg book
Format: Paperback, Format: Paperback
I've taken a couple classes on SQL some time ago and was looking for a book to go over basics. This is a perfect book to start with the basics of understanding how to write a SQL query. I really liked that there is a free database to use in SQLite to follow along with the examples in the book. That was very helpful for me. I appreciated the tips throughout the chapters and the practice questions at the end. Easy to read and follow.

This is a good very distant overview
Format: Paperback
Sometimes I need a really simplistic overview of an entire subject before I feel comfortable sitting down to learn it. Like if you are going to learn about, say, 13th Century France you might want to know just a little about the major issues of the entire century before sitting down with a text book. This book is good for that. It's short, it gets you started with the main keywords, and at the end you have a good picture of what the language can do. And you can get to the end in a day or two. It's very well written, well organized, clear, and very very limited in scope. But if you read it, you will be in good shape to start getting down to business with working with SQL with a more advanced text. This book, in my opinion, was well worth the money and the read even though ultimately I turned to something far more advanced.
