的MySQL連接兩個表MAX（值）

Question

我有這樣的MySQL代碼女巫工作得很好

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

我怎樣才能將這個選擇與用戶表ON users.id = auction.uid？

謝謝

Answer 1

您可以使用加入爲你的查詢可能看起來像

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

Answer 2

我在這裏看不到任何魔法：

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
