This tutorial shows you how to use the SQL Tuning Advisor feature in Oracle SQL Developer 3.2.

In this tutorial you will use SQL Developer to generate and display the explain plan of a SQL query and execute an autotrace plan. In addition, you examine the effects of changing column order in a composite index and use SQL Plan Baseline to associate a hinted execution plan with a hard coded SQL statement.

In this tutorial using SQL Developer, you will use the Optimizer Access Paths to examine a number of scenarios.

In this tutorial, you learn how to use Express Edition to access, query, and manipulate data in the Express Edition database.

Without proper safeguards, applications are vulnerable to various forms of security attack. One particularly pervasive method of attack is called SQL injection. Using this method, a hacker can pass string input to an application with the hope of gaining unauthorized access to a database. By taking this self-study tutorial, you can arm yourself with techniques and tools to strengthen your code and applications against these attacks. This tutorial employs text and diagrams to present concepts, design issues, coding standards, processes, and tools. Flash-based demos and simulations allow you to visualize what you have learned, and assessment quizzes help you gauge your learning progress.
