Introduction
Welcome to the world of relational databases and SQL! This book is written for those selfmotivatedindividuals out there who would like to get an edge on relational database technology by learning the Structured Query Language—SQL. This book was written primarilyfor those with very little or no experience with relational database management systemsusing SQL. This book also applies to those who have some experience with relational databasesbut need to learn how to navigate within the database, issue queries against the database,build database structures, manipulate data in the database, and more. This book isnot geared toward individuals with significant relational database experience who havebeen using SQL on a regular basis.
What This Book Intends to Accomplish
This book was written for individuals with little or no experience using SQL or those whohave used a relational database, but their tasks have been very limited within the realm ofSQL. Keeping this thought in mind, it should be noted up front that this book is strictly alearning mechanism, and one in which we present the material from ground zero and provideexamples and exercises with which to begin to apply the material covered. This book isnot a complete SQL reference and should not be relied on as a sole reference of SQL.However, this book combined with a complete SQL command reference could serve as acomplete solution source to all of your SQL needs.
What We Added to This Edition
This edition contains the same content and format as the first through third editions. Wehave been through the entire book, searching for the little things that could be improved toproduce a better edition. We have also added concepts and commands from the new SQLstandard, SQL:2003, to bring this book up to date, making it more complete and applicableto today’s SQL user. The most important addition was the use of MySQL for hands-on exercises.By using an open source database such as MySQL, all readers have equal opportunityfor participation in hands-on exercises.
