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.

What can you do when database performance doesn't meet expectations? Before you turn to expensive hardware upgrades to solve the problem, reach for this book. Refactoring SQL Applications provides a set of tested options for making code modifications to dramatically improve the way your database applications function. Backed by real-world examples, you'll find quick fixes for simple problems, in-depth answers for more complex situations, and complete solutions for applications with extensive problems. Learn to: Determine if and where you can expect performance gains Apply quick fixes, such as limiting calls to the database in stored functions and procedures Refactor tasks, such as replacing application code by a stored procedure, or replacing iterative, procedural statements with sweeping SQL statements Refactor flow by increasing parallelism and switching business-inducted processing from synchronous to asynchronous Refactor design using schema extensions, regular views, materialized views, partitioning, and more Compare before and after versions of a program to ensure you get the same results once you make modifications Refactoring SQL Applications teaches you to recognize and assess code that needs refactoring, and to understand the crucial link between refactoring and performance. If and when your application bogs down, this book will help you get it back up to speed.

Transact-SQL is a procedural language used on both Microsoft SQL Server and Sybase SQL Server systems. It is a full-featured programming language that dramatically extends the power of SQL (Structured Query Language).The language provides programmers with a broad range of features, including: A rich set of datatypes, including specialized types for identifiers, timestamps, images, and long text fieldsLocal and global variablesFully programmable server objects like views, triggers, stored procedures, and batch command filesConditional processingException and error handlingFull transaction controlSystem stored procedures that reduce the complexity of many operations, like adding users or automatically generating HTML Web pagesIn recent years, the versions of Transact-SQL have diverged on Microsoft and Sybase systems; the book explains the differences. It also contains up-to-the-minute information on the latest versions: Microsoft SQL Server versions 6.5 and 7.0 and Sybase version 11.5.A brief table of contents follows: PART I: The Basics: Programming in Transact-SQL1.
