Update vbulletin setting array !

[K a M a L]

Welcome all ;
I'm creating an admin page to control setting of a plugin
I use a query
$db->query_write("UPDATE " . TABLE_PREFIX . "setting
SET value = ".$recusergroup."
WHERE varname ='reccreate2'");
the setting is updated in setting table but when I call $vbulletin->options['reccreate2']
I get the old value not the updated one
I think the setting is cached somewhere or stored at another table
my question is what to do to update the setting

The values are cached in the datastore table. You can call the function build_options() (in includes/adminfunctions.php) after writing the change to your setting.
