刪除涉及連接表的行

Question

如何從我提供「Tim」（WHERE userName ='Tim'）時訂購的產品中刪除userID 00002。不是用戶ID，我非常瞭解它。

User Info 
------------------ 
userID | userName 
00001 | Jim 
00002 | Tim 
00003 | Steve 
00004 | Boo 

Product Ordered 
------------------ 
userID | ProductCode 
00002 | p0001 
00002 | p0003 
00001 | p0002 
00003 | p0001 

Answer 1

DELETE po.* 
FROM `Product ordered` po 
INNER JOIN `User Info` ui 
    ON ui.userID = po.userID 
WHERE ui.userName = 'Tim' 

應該這樣做。

Answer 2

DELETE FROM product_ordered 
WHERE userID IN (
    SELECT userID FROM user_info 
    WHERE userName='Tim' 
)
