获取数据库倒序排列orderBy怎么写？
orderByASC('xxx', false)
$update = $iot->select('*')->from('iot_motherboard_update')->where('type = "'.$ret.'"')->orderByASC(‘did',false)->row();
是这样么？
补充：gatewayWorker下Event.php中
orderByASC('xxx', false)
$update = $iot->select('*')->from('iot_motherboard_update')->where('type = "'.$ret.'"')->orderByASC(‘did',false)->row();
