Instead of needing a tool like <a href="http://www.phpmyadmin.net/home_page/index.php" rel="nofollow ugc">phpMyAdmin</a> 
or the mysql command line client to view and modify your WordPress database, 
the SQL Executioner allows you to run arbitrary SQL queries against your 
WordPress database from within the Admin. In many cases this allows you to bypass 
the inherent limitations of the WordPress Admin interface, and use the full expressive 
power of SQL to analyze and update your blog’s database.
To use simply install and visit the Tools > SQL Executioner page.
