Как в друпале правильно выполнять SQL запросы?

пробую так
<?php
$result = db_query_range("SELECT users.uid AS uid,
users.name AS users_name,
og_uid.is_admin AS og_uid_is_admin,
og_uid.created AS og_uid_created
FROM shvabra_users users
LEFT JOIN shvabra_og_uid og_uid ON users.uid = og_uid.uid
LEFT JOIN shvabra_node node_og_uid ON og_uid.nid = node_og_uid.nid
WHERE (users.status <> 0) AND (og_uid.is_active <> 0) AND (og_uid.is_admin in ('0', '1')) AND (og_uid.nid = %d)
ORDER BY og_uid_created DESC", $node->nid);
while($nod = db_fetch_object($result)) {
print_r($nod, 1);
};

?>
