Structured Query Language has become the standard for generating, manipulating, and retrieving database information. The dramatic increase in the popularity of relational databases, coupled with Oracles having the largest market share, has created a demand for programmers who can write SQL code correctly and efficiently. This book provides a systematic approach to learning SQL in Oracle. Each chapter is written in a step-by-step manner and includes examples that can be run using Oracle. Using the sample tables and data provided, readers will be able to perform the examples to gain hands-on experience with Oracle programming. Specifically, this book will help you: * Gain an understanding of basic SQL principles. * Learn to generate, store, and edit SQL queries in Oracle. * Develop joins, subqueries, and correlated subqueries. * Work with XML and Oracle databases. * Test your SQL knowledge with the exercises at the end of each chapter.
