Summary: Wonderful Books for Mild "ADHD" Folks
Comment: Packed with needed knowledge in humorous manner! It is way easier to read than any SQL I have ever encountered... wonderful job done. I will definitely look at the books in the series first before I buy computer books of other technologies from now on.

Summary: Average Introduction to SQL ... Subpar for Technical Readers
Comment: Before purchasing this book, I read the reviews and was instantly hooked on the concept of a technical book that would use humor, imagery and other off-beat approaches as teaching tools. Unfortunately, after reading the entire book I feel that these techniques were way over utilized. The figures are very busy because the author feels you will remember words if they are attached to an image. In addition there is very little information conveyed on each page. I found myself thinking "why doesn't the author just get to the point already instead of making me flip through 10 pages?" The book probably could have been condensed down to a half or quarter of its size. The "exercises" are also quite uninspired. I didn't learn anything more from them than I would reading an intro to SQL webpage.
Anyone who has a technical background such as engineering or computer science will probably feel the same as I do. However, for those who have weak or moderate computer language skills may find the book a breath of fresh air as compared to dry, boring long-winded textbooks. I would strongly recommend reading through the first chapter if at all possible to determine if the teaching style is a good fit for you. Do a search on the net as the first chapter is freely available. I learned this after I bought the book!

Summary: Expected more content for length
Comment: This book is an excellent book for beginners to SQL that have a tough time using books to technology. The book is a very long read if you are already comfortable basic concepts like joins. However, it does have good chapters on table and database design. For the length of the book, I expected more advanced topics like stored procs.

Summary: Unorthodox & Effective Training Method
Comment: At first I was a little thrown off by all the images and quips (I guess I'm used to boring, dry guides). After a while I was actually drawn into the book and how it guided me through learning SQL. I must admit that I had a somewhat rudimentary understanding of SQL but after completing the book my queries a sharper & more complex.
I do want to put it out there; this isn't really a reference book, it's primary focus is to teach you the fundamentals of SQL, not really the fancier functions or tricks that you can use in SQL.
There was only one short coming to the book; some of the samples did not contain answers. I know it's petty, but there were times I would've liked to have known the answers.
I would confidently recommend this book to anyone looking to learn SQL.

Summary: Great Book for Basic SQL concepts
Comment: If there is one book in head first that deserves attention (apart from Servlets book) it is this. All the programming books are great anyways (Exception is Head First Design patterns, PLEASE DONT BUY that one!).
SQL Head first helps in visually knowing what is going to happen, especially when running mutltiple OUTER JOINs and writing subqueries etc. Thanks to this book (and a combination of SQL Cookbook and SQL Tuning (for more advanced people)).
Here are some of positives of this book :
1.) Starts out at very basic level (this can be annoying for some folks, who already know much of the stuff, but then this book is not for you then, try SQL Cookbook or SQL Tuning). I would still say this book can be kept as a good reference, as even seasoned people can be helped from visually organized "notes" in there.
2.) Advanced Select section is awesome, JOINS and subqueries and Associations are explained very well. (In this case diagrams help in better visualizing things and helped me understand and recall the concepts really well, After a long time i am not trying to "remember" what the syntax of a clause is in SQL, instead i just visualize things (an example of this would be a sum(xxx) and a group by ... and how the diagram illustrates it very neatly, if i want to use a complex JOIN query or a multiple group by, i don't have to google anymore).
Cons :
1.) Some of topics could have been covered in a better way, example tuning etc.
2.) is @ medium level, for advanced topics i still refer to SQL cookbook or tuning book (by Dan).
All in all it was a great buy for me.
