如何在MySQL中獲取MAX（速度）的時間值？

Question

我有一個表結構如下：

Id | Speed | Time 

我想包含的最大速度行的時間。

我的示例查詢不會返回正確的記錄。

SELECT MAX(speed), time FROM info WHERE id = 1 AND time > 1234 

Answer 1

你可以命令的結果，並採取的第一條記錄：

SELECT speed, time 
FROM  info 
WHERE id = 1 AND time > 1234 
ORDER BY speed DESC 
LIMIT 1 

Answer 2

SELECT MAX(speed) as speed, time FROM info WHERE id = 1 AND time > 1234 ORDER BY id 

也許你試圖讓列中取壞。所以請嘗試給一個別名使用它作爲列名。

或者嘗試，因爲獲得最大的子查詢的條件值：

SELECT * FROM info WHERE id = 1 AND speed = (SELECT MAX(speed) FROM info) AND time>1234; 

Answer 3

select id, speed, time 
    from info 
where speed = (select max(speed) 
        from info);
