If you want to edit and entry *in the database*, then you need to do a query like this (example to set userid to 10 for a user who's username is JoeBlow:

PHP Code:

$db->query_write("
    UPDATE TABLE " . TABLE_PREFIX . "user
    SET userid=10
    WHERE username='JoeBlow'
");

(I would NOT change the userids via a query. If you accidentally set the userid to the same as another user, you can really mess things up!)
