如何用JOIN和ID刪除？

Question

下面的查詢得到的我要刪除的記錄列表...

SELECT * 
FROM `orderitems` as oi 
LEFT JOIN `orders` as o 
    ON (o.`orderid` = oi.`orderid`) 
WHERE o.`date` = '2012-10-05' 
    AND o.`status` = 'init'; 

不幸的是，表格設計沒有id場。
我看過其他刪除與連接，但都使用id字段。
這不起作用：

DELETE 
FROM `orderitems` as oi 
LEFT JOIN `orders` as o 
    ON (o.`orderid` = oi.`orderid`) 
WHERE o.`date` = '2012-10-05' 
    AND o.`status` = 'init'; 

一個人怎麼DELETE上面鑲有一個MySQL查詢？ （無PHP）

Answer 1

試試這個，

DELETE oi -- add the alias here 
FROM `orderitems` as oi 
LEFT JOIN `orders` as o 
    ON (o.`orderid` = oi.`orderid`) 
WHERE o.`date` = '2012-10-05' 
    AND o.`status` = 'init'; 

，或者使用子查詢

DELETE FROM `orderitems` 
WHERE `orderid` IN 
(
    SELECT o.`orderid` 
    FROM `orders` as o 
    WHERE o.`date` = '2012-10-05' AND o.`status` = 'init' 
)
