|
|
<p><span class="bold">Multiple grants:</span> If you revoke a privilege on a package,
|
||
|
|
it nullifies any grant of the privilege on that package, regardless of who
|
||
|
|
granted it.</p>
|
||
|
|
<p><span class="bold">Revoking WITH GRANT OPTION:</span> The only way to revoke
|
||
|
|
the WITH GRANT OPTION is to revoke ALL.</p>
|
||
|
|
<p><span class="bold">Privilege warning:</span> Revoking a specific privilege
|
||
|
|
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 package
|
||
|
|
privilege is revoked, the corresponding system authorities are revoked. For
|
||
|
|
information on the system authorities that correspond to SQL privileges see <a href="rbafzmstgntpp.htm#gntpp">GRANT (Package Privileges)</a>.</p>
|
||
|
|
<p><span class="bold">Syntax alternatives:</span> The following keywords are synonyms
|
||
|
|
supported for compatibility to prior releases. These keywords are non-standard
|
||
|
|
and should not be used:</p>
|
||
|
|
<ul>
|
||
|
|
<li>The keyword RUN can be used as a synonym for EXECUTE.</li>
|
||
|

<li>The keyword PROGRAM can be used as a synonym for PACKAGE.</li></ul>
