If you get a permissions error do the following:

In the vB3 Admin CP:

To run a single query you first need to give yourself permission to run queries in the Admin CP. To do this, edit this section of config.php:

    //    ****** USERS WITH QUERY RUNNING PERMISSIONS ******
    //    The users specified here will be allowed to run queries from the control panel.
    //    See the above entries for more information on the format.
    //    Please note that the ability to run queries is quite powerful. You may wish
    //    to remove all user IDs from this list for security reasons.
$config['SpecialUsers']['canrunqueries'] = '';

...with x being your userid number. Then try again.
