PEAR : LimitQuery and getAll

[Mos]

Hello!
Do you know how to collect results from a [PEAR]LimitQuery() based request
in an array ? (like a getAll for example ?)

example :
$result=& $db->limitQuery($query, $from, $cpt);
if (DB::isError($result)) {die($result->getMessage());}
$result2=& $result->getAll();

But with that an error occurs : Fatal error: Call to undefined function:
getall() in (...)\supportfunctions.php on line (...)

Is it possible to collect theses data or should I use while....
fetchRow()... only ?

Merci

Mos
