Joe Celko’s SQL Puzzles and Answers, Second Edition, Second Edition (The Morgan Kaufmann Series in Data Management Systems) (Paperback)
by Joe Celko (Author)
This book is for all of them who enjoy little puzzles or just something which gives them challenge. Some puzzles took hours to solve and some were straight forward. This book teaches you some basic principles and patterns as well satisfy your need for brain teasers.
This book for all the SQL programmers regardless of database language you prefer. Book contains examples in different languages (SQL Server, Oracle, Sybase, Informix etc). If reader is absolute beginner this book is not what reader needs to start. This book is perfect for someone who has industry experience or has deep understanding of different SQL concepts.
This book contains 75 different puzzles. Each puzzle starts with puzzle definition or question and follows by multiple answers. Answers vary by either techniques or programming languages, in many cases both. Puzzles contained in this book are like typical day to day work problems, many time any developer can find the solution if they spend some time on it. However, some problems are quite unique in their own way and reading them gives broader idea of database programming.
One thing I will note about book is the quality of the puzzle, as other reviewer has noted some puzzles are just not puzzle but simple problems which can be solved easily by experienced developer. Not all developers are on same level and I am sure every reader has their own opinion and choice.
The idea on which the book is written is very simple – “Think out of the box”. The problems are real, the solutions are real and multiple answers from wide verity of participants – this makes this book worth the time. Every solution has its own flair and taste. If any problem is attempted with right technique and sound theory it is always easy to reach resolution.
There is no source code available to download for this book so reader will have to write everything by their own. It is good in one way as ideally all readers should try to solve each puzzles by their own, however, source code will sure help many ways.
Rating: 4 Stars
Summary: I think this book should be there available for every database developer who has reached advanced level. If developer can solve most of the puzzles from this book he sure is advanced level developer, if not while trying to solve them he will reach advanced level.
