我需要所有会员资格，他们的订单和最新的历史记录状态。 我正在努力：

$alias = $query->getRootAlias();

    $query->innerJoin (\"$alias.Order o\")
    ->select(\"o.id,o.*\")
    ->addSelect(\"(select os.order_status_name from JosVmOrderStatus os inner join os.JosVmOrderHistory oh on os.order_status_id=oh.order_status_id where oh.order_id=o.order_id order by oh.date_added desc limit 1)\");

但是我无法让addSelect接受联接。最新错误消息是“找不到操作系统类” 我正在使用Doctrine 1.2
