In just 24 lessons of one hour or less, you will learn professional techniques to design and build efficient databases and query them to extract useful information. Using a straightforward, step-by-step approach, each lesson builds on the previous one, allowing you to learn the essentials of ANSI SQL from the ground up.

Example code demonstrates the authors’ professional techniques, while exercises written for MySQL offer the reader hands-on learning with an open-source database. Included are advanced techniques for using views, managing transactions, database administration, and extending SQL.

Step-by-step instructions carefully walk you through the most common SQL tasks.

Q&As, Quizzes, and Exercises at the end of each chapter help you test your knowledge.

Notes and Tips point out shortcuts and solutions.

New terms are clearly defined and explained.

Learn how to…

  • Use SQL-2003, the latest standard for the Structured Query Language
  • Design and deploy efficient, secure databases
  • Build advanced queries for information retrieval
  • Sort, group, and summarize information for best presentation
  • Tune databases and queries for maximum performance
  • Understand database administration and security techniques

For more than ten years the authors have studied, applied, and documented the SQL standard and its application to critical database systems.
