Webmin provides a simple interface to your MySQL database server that allows you to execute arbitrary SQL commands. This can be a useful feature when you want to quickly find something in a database or perform a bulk update of multiple rows of data.
Follow these steps to execute an SQL command on your database:
Navigate to Servers | MySQL Database Server.
Click the icon that represents the database you would like to use, for instance,
mysql.Click the Execute SQL button.
Enter an SQL command in the text area, for instance:
SELECT host,user FROM user;
Click the Execute button.
You will be presented with a sortable display of data returned by the SELECT command.
