mysql - MySQL 用 min 选择

Question

我需要选择字段message并username从表列表中选择list_id=1（可以是 2 或 5 等）且具有最小数值（min（number））。我该怎么做？我尝试过这个：

SELECT `message`,`username` FROM `list` WHERE `list_id`=2 AND min(`number`)

但它不起作用。

Answer 1

试试看

SELECT `message`,`username`
FROM `list`
WHERE `list_id` = 2
ORDER BY `number` ASC
LIMIT 1

Answer 2

SELECT 
    a.*
FROM list
INNER JOIN   (
     SELECT 
          `message`,
          `username`,
          MIN(`number`) 
     FROM `list` 
     WHERE `list_id`=2 
    ) as a on a.id = list.id
