This is a very nice book! I used it to increase the SQL level of my employees. We did two puzzles a week, and compared our answers. And it sure helped. But there are some buts in this story. First, the puzzles are not always defined well, so you do not know what to do before you see the discussion in the answer part. Second, a lot of the solutions are not very good. Whenever I found a better one, I mailed Joe Celko. Every time he replied to me (very nice!) that somebody else also pointed it out and that there were even better solutions that mine. This means that the solutions are not always that good in the book. But still, it has alo of good brainteasers. But try them first yourself before looking to the answers as your answer could be better.

Joe Celko gibt mit diesem Buch einen auf seine Weise übliche legere Art Anregungen bei der Lösung von Problemen sich mehr als einmal die Frage zu stellen: Was will ich wirklich?
Die Puzzels sind klar fomuliert und werden jeweils auf sehr unterschiedliche Weise gelöst, oder vielleicht doch nicht, was wollte Joe nochmal ?
Jedenfalls ist dies ein großartiges Buch, um auf eine entspannte Art SQL kennen und denken zu lernen.

The hidden jewel of the Celko trilogy, this is one of my favorite SQL books. It takes the concepts in Celko's seminal work, SQL for Smarties, and illustrates how to apply them to solve real-world problems. As always, the book is rife with tales from Celko's long and varied career in the SQL trenches, as well as the subtle witticism for which he is famous. Like all great technical books - it's timeless - the techniques you learn today will work tomorrow because Celko follows the ANSI/ISO standard to the letter. As a fellow author, I can appreciate the work that went into writing this book - real examples require real work, especially by the author. This book belongs in the library of every would-be SQL practitioner.

This book contains a set of problems to be solved using SQL, and the problems are such that they make the reader think of SQL and use it in a set based manner as opposed to mixing in procedural techniques.
A stellar book for instruction is SQL, as not only do the problems teach about how to solve SQL problems correctly, but many of the problems are quite difficult, providing for major mind expanding opportunities.
Definitely worth the money if you have an SQL package to attempt to solve the problems with.
