This tab allows you to grant privileges on a schema level. In MySQL, a schema is the same as a database. To grant privileges for a specific database, click on the database name in the left box. (You cannot select more than one database at a time.)
Privileges not assigned to the user are listed under Available Privileges. You can remove privileges by selecting them in the left box, and then clicking the button. Removed privileges will appear in the Available Privileges box. You can assign privileges by selecting them in the Available Privileges box, and then clicking the button.
