mysql用MAX連接兩個表（值）

Question

我有這個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

如何將此選擇與用戶表ON users.id = auction.uid連接？

謝謝

Answer 1

我在這里看不到任何魔法：

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

您可以使用聯接來查詢您的查詢

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

要么

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

根據您的需要添加聯接詳細信息
