<p><span class="bold">Multiple grants:</span> If authorization ID A granted the

from B nullifies all those grants.</p>
|

the WITH GRANT OPTION is to revoke ALL.</p>

from a user does not necessarily prevent that user from performing an action

that requires that privilege. For example, the user may still have the privilege
|

through PUBLIC or administrative privileges.</p>
|

<p><span class="bold">Corresponding system authorities:</span> When a distinct type privilege

is revoked, the corresponding system authorities are revoked. For information

on the system authorities that correspond to SQL privileges see <a href="rbafzmstgntudtp.htm#gntudtp">GRANT (Distinct Type Privileges)</a>.</p>
