This plugin will allow you to execute any type of SQL query into the WordPress’s DB connecting through the driver provided by the MySQLi extension without the need to use another tool like phpMyAdmin.
It also gives you the ability to export the results in a CSV format file.
In order to access this plugin’s admin page (Tools -> Run SQL Query), your account needs to have the <code>install_plugins</code> capability, that means a Super Admin in the multi-site installation or an Admin in a single site.
