我无法获取主 id 数组,我尝试调试它在使用 joinLeft 函数时发生
这是我的脚本
//setIntegrityCheck to false to allow joins
$roomModel = new self();
$select = $roomModel->select(Zend_Db_Table::SELECT_WITH_FROM_PART)
->setIntegrityCheck(FALSE);
//performs join aliasing table room_type to t
$select->join(array('t' => 'room_types'), 't.room_type_id = rooms.room_type_id AND num_beds> '.$number_beds);
////performs join aliasing table room_status to s
$select->join(array('s' => 'room_statuses'), 's.room_status_id = rooms.room_status_id');
$select->joinLeft(array('chin' => 'checkin'), 'chin.checkin_date > '.$checkin.' AND chin.checkin_date <'.$checkout.'');
$select->joinLeft(array('chout' => 'checkout'), 'chout.checkout_date >'.$checkin.' AND chout.checkout_date <'.$checkout.'');
$result = $roomModel->fetchAll($select);
是什么导致它发生?
