The Language of SQL


The Language of SQL, Second EditionMany SQL texts attempt to serve as an encyclopedic reference on SQL syntax -- an approach that is often counterproductive, because that information is readily available in online references published by the major database vendors. 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 organized 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, and instructions are included on how to obtain and install free versions of the databases. This is the only book you need to gain a quick working knowledge of SQL and relational databases.Learn How To...Use SQL to retrieve data from relational databasesApply functions and calculations to dataGroup and summarize data in a variety of useful waysUse complex logic to retrieve only the data you needUpdate data and create new tablesDesign relational databases so that data retrieval is easy and intuitiveUse spreadsheets to transform your data into meaningful displaysRetrieve data from multiple tables via joins, subqueries, views, and set logic Create, modify, and execute stored proceduresInstall Microsoft SQL Server, MySQL, or OracleContents at a Glance1 Relational Databases and SQL2 Basic Data Retrieval3 Calculated Fields and Aliases4 Using Functions5 Sorting Data6 Selection Criteria7 Boolean Logic8 Conditional Logic9 Summarizing Data10 Subtotals and Crosstabs11 Inner Joins12 Outer Joins13 Self Joins and Views14 Subqueries15 Set Logic16 Stored Procedures and Parameters17 Modifying Data18 Maintaining Tables19 Principles of Database Design20 Strategies for Displaying DataA Getting Started with Microsoft SQL ServerB Getting Started with MySQLC Getting Started with Oracle
