You know the rudiments of the SQL query language, yet you feel you aren?????t taking full advantage of SQL?????s expressive power. You?????d like to learn how to do more work with SQL inside the database before pushing data across the network to your applications. You?????d like to take your SQL skills to the next level.

Let?????s face it, SQL is a deceptively simple language to learn, and many database developers never go far beyond the simple statement: SELECT FROM WHERE . But there is so much more you can do with the language. In the SQL Cookbook, experienced SQL developer Anthony Molinaro shares his favorite SQL techniques and features. You?????ll learn about:

* Window functions, arguably the most significant enhancement to SQL in the past decade. If you?????re not using these, you?????re missing out
* Powerful, database-specific features such as SQL Server?????s PIVOT and UNPIVOT operators, Oracle?????s MODEL clause, and PostgreSQL?????s very useful GENERATE_SERIES function
* Pivoting rows into columns, reverse-pivoting columns into rows, using pivoting to facilitate inter-row calculations, and double-pivoting a result set
* Bucketization, and why you should never use that term in Brooklyn.
* How to create histograms, summarize data into buckets, perform aggregations over a moving range of values, generate running-totals and subtotals, and other advanced, data warehousing techniques
* The technique of walking a string, which allows you to use SQL to parse through the characters, words, or delimited elements of a string

Written in O?????Reilly?????s popular Problem/Solution/Discussion style, the SQL Cookbook is sure to please. Anthony?????s credo is: ???When it comes down to it, we all go to work, we all have bills to pay, and we all want to go home at a reasonable time and enjoy what?????s still available of our days.??? The SQL Cookbook moves quickly from problem to solution, saving you time each step of the way.

The Art of SQL by Stephane Faroult, Peter Robson
Publisher: O?????Reilly Media, Inc.; 1 edition (March 1, 2006)
367 pages; Language: English; ISBN: 0596008945

For all the buzz about trendy IT techniques, data processing is still at the core of our systems, especially now that enterprises all over the world are confronted with exploding volumes of data. Database performance has become a major headache, and most IT departments believe that developers should provide simple SQL code to solve immediate problems and let DBAs tune any ???bad SQL??? later.

In The Art of SQL, author and SQL expert Stephane Faroult argues that this ???safe approach??? only leads to disaster. His insightful book, named after Art of War by Sun Tzu, contends that writing quick inefficient code is sweeping the dirt under the rug. SQL code may run for 5 to 10 years, surviving several major releases of the database management system and on several generations of hardware. The code must be fast and sound from the start, and that requires a firm understanding of SQL and relational theory.

The Art of SQL offers best practices that teach experienced SQL users to focus on strategy rather than specifics. Faroult?????s approach takes a page from Sun Tzu?????s classic treatise by viewing database design as a military campaign. You need knowledge, skills, and talent. Talent can?????t be taught, but every strategist from Sun Tzu to modern-day generals believed that it can be nurtured through the experience of others. They passed on their experience acquired in the field through basic principles that served as guiding stars amid the sound and fury of battle. This is what Faroult does with SQL.

Like a successful battle plan, good architectural choices are based on contingencies. What if the volume of this or that table increases unexpectedly? What if, following a merger, the number of users doubles? What if you want to keep several years of data online? Faroult?????s way of looking at SQL performance may be unconventional and unique, but he?????s deadly serious about writing good SQL and using SQL well. The Art of SQL is not a cookbook, listing problems and giving recipes. The aim is to get you-and your manager-to raise good questions.
