Every IT professional needs at least a basic understanding of SQL. A Visual Introduction to SQL, Second Edition provides a unique tool for acquiring this knowledge.

For this new edition of their successful, long-selling book, David Chappell and J. Harvey Trimble Jr. have updated the contents to reflect SQL today. The result is a clear, step-by-step explanation of the current language, with the book's unique visual approach guiding the way.
