删除涉及表的连接的行

Question

当我提供“Tim”（WHERE userName ='Tim'）时，如何从订购的产品中删除用户ID 00002。不是userID，我很清楚它。

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'

应该这样做。

Answer 2

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