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.)
      You may use wild cards to grant privileges on a number of schemata
      simultaneously. Use “%” to replace
      multiple characters and “_” to
      replace a single character. To use this feature, right click any
      database name in the schemata list, choose the Add Schema
      with Wildcards option from the pop-up menu and enter the
      pattern you wish to match. Entering m% for
      example, will add the entry, m% to the schemata
      list. Highlight this entry and any privileges granted will be
      granted for all schemata starting with the letter
      “m”.
    
This pop-up menu option is only available under Windows.
        If wild card characters appear in schemata names, you may escape
        them using the “\” character.
      
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.
      The Schema Privileges tab only displays
      privileges that have been granted for a specific schema. No schema
      privileges will show in the Assigned
      Privileges column for users with global privileges. For
      example, the Assigned Privileges column will
      be blank for a root user with global privileges
      on all schemata. Likewise, the Assigned
      Privileges column will be blank for a user with a
      global SELECT privilege, unless
      SELECT has also specifically been granted for
      the currently selected schema.
