Doctrine 2.0 native query without mapping - oracle

Question

I am writing a tiny little migration script and i am only trying to update one attribute of one element.
The Result i need has no Representation in the local Environment, so what i would need is a very simple SQL (here it is Oracle) handler that i can iterate over and get an array returned.
Is that possible with doctrine?
i.e. i would want to do this:
$query = "SELECT t2.status FROM t2 LEFT JOIN t1 ON t1.id = t2.foreinkey";
$iterator = $connection->execute($query)->iterate();
foreach ($iterator as $array) {
// do something with an associative array
}
UPDATE / SOLUTION:
With the Hint from Corbin i came up with this Solution which works pretty fine:
$query = "SELECT t2.status FROM t2 LEFT JOIN t1 ON t1.id = t2.foreinkey";
$iterator = $connection->query($query);
while (is_object($iterator) AND ($array = $iterator->fetch()) !== FALSE) {
// do something with an associative array
}

If you want to do any mapping.
Another option would be to get the connection object from EntityManager::getConnection and operate on it.
It returns a Doctrine\DBAL\Connection which you should be able to work with. It has the typical fetchColumn fetchArray fetchAssoc so on.
