The complete reference SQL

Abstract

What is SQL and where did it come from? How do the SQL tools vary across database applications from different vendors? How will SQL change in the future? You'll find the answers to all these questions and many more in SQL: The Complete Reference. Much more than just a listing of SQL commands and their parameters, this encyclopedic reference guide explains the concepts and constructs of SQL programming such that non-technical readers will understand them and technical readers won't be bored.
