解决ERROR 1109 (42S02): Unknown table 'xxx' in MULTI DELETE

我碰到的情况是这样的使用Mysql，有三个表分别是order、order_item和user，想同时删除用户以及用户订单和订单详情里的内容，执行下边的sql导致该错误

DELETE user,order,order_item
FROMuser as u
LEFT JOIN order as o ONu.uid=o.uid
LEFT JOIN order_item as i ONo.oid=i.oid
WHEREu.uid=1

解决办法是在DELETE后使用别名

DELETE u,o,i
FROMuser as u
LEFT JOIN order as o ONu.uid=o.uid
LEFT JOIN order_item as i ONo.oid=i.oid
WHEREu.uid=1
