Language of SQL, The, 2nd edition

For SQL beginners, it's more important for a book to focus on general concepts and to offer clear explanations and examples of what various SQL statements can accomplish. This is that book.
A number of features make The Language of SQL unique among introductory SQL books. First, you will not be required to download software or sit with a computer as you read the text. The intent of this book is to provide examples of SQL usage that can be understood simply by reading.
Second, topics are organised in an intuitive and logical sequence. SQL keywords are introduced one at a time, allowing you to grow your understanding as you encounter new terms and concepts.
Finally, this book covers the syntax of three widely used databases: Microsoft SQL Server, MySQL, and Oracle. Special 'Database Differences' sidebars clearly show you any differences in syntax among these three databases.
