If you've ever used a relational database product, chances are that you're already familiar with SQL the internationally-accepted, standard programming language for databases whic is supported by the vast majority of relational database management system (DBMS) products available today. You may also have noticed that, despite the large number of "reference" works that claim to describe standard SQL, not a single one provides a complete, accurate and example-filled description of the entire SQL Standard. This book was written to fill that void.
