Elegant and descriptive, SQL has long been the essential language for relational databases, but it's a complex language to learn and use. Ideal for experienced programmers, analysts, and database administrators, this comprehensive reference guide clearly documents every SQL command and reference with practical examples that illustrate important concepts and uses. It's a wealth of information packed into a succinct, comprehensive, and easy-to-use format.
The updated fourth edition of SQL in a Nutshell explains how to implement SQL in leading commercial and open source database products, such as Oracle, DB2, SQL Server, and MySQL.
The author clearly states in the preface what this book is, and is not. The book is primarily a command reference. It is intended as a reference tool, not a tutorial. Nor is it expository.
This is useful ONLY as a reference. Its organization is utterly useless unless you already know SQL top to bottom and just need a refresh on the fiddly bits. That said, if the above is what you're looking for, it is good at that job.
