的MySQL连接两个表MAX（值）

Question

我有这样的MySQL代码女巫工作得很好

SELECT uid , MAX(value) AS bidvalue FROM auction 
WHERE pid = '$pid' and max_bid=0 
GROUP BY uid 
ORDER BY bidvalue DESC 
LIMIT 1 

我怎样才能将这个选择与用户表ON users.id = auction.uid？

谢谢

Answer 1

您可以使用加入为你的查询可能看起来像

SELECT uid, users.name, MAX(value) AS bidvalue 
FROM auction 
INNER JOIN users ON users.id = auction.uid 
WHERE pid = '$pid' and max_bid=0 
GROUP BY uid 
ORDER BY bidvalue DESC 
LIMIT 1 

或

SELECT uid, users.name, MAX(value) AS bidvalue 
FROM auction 
OUTER JOIN users ON users.id = auction.uid 
WHERE pid = '$pid' and max_bid=0 
GROUP BY uid 
ORDER BY bidvalue DESC 
LIMIT 1 

with the joins details as per your need

我在这里看不到任何魔法：

SELECT uid, users.name, MAX(value) AS bidvalue 
FROM auction 
INNER JOIN users ON users.id = auction.uid 
WHERE pid = '$pid' and max_bid=0 
GROUP BY uid 
ORDER BY bidvalue DESC 
LIMIT 1
