Get up to speed fast with SQL, the language of databases. Bestselling author Chris Fehily teaches you just the parts of SQL that you need to know. Quick, learn-by-example lessons start with simple data retrieval and sorting, move on to filtering and grouping, and then build to more-advanced topics, including joins, subqueries, views, and transactions. Whether you're an analyst, programmer, webmaster, or personal user, you'll find straightforward, practical answers. You can download the sample database to follow along with the examples.

  • Learn the core language for standard SQL, and variations for the most widely used database systems.
  • Organize your database in terms of the relational model.
  • Master tables, columns, rows, and keys.
