获得MySQL的最佳射手

Question

我有简单的表格：

ID    Score
1     90
2     85
3     96
4     96
5     73

我想获得最佳射手，所以我使用了最大功能：

select max(s.score) as score,
    s.id
from student_score as s

结果：

score    id
96       1

问题是，有两名得分手，我将如何获得所有最佳得分手？

Answer 1

子查询从表student_score获得最高分，其结果将用于比较WHERE子句。

SELECT a.*
FROM student_score a
WHERE Score = 
(
    SELECT MAX(Score)
    FROM student_score
)

• See SQLFiddle Demo

Answer 2

select s.score, s.id
from student_score as s
where
    s.score in 
    (
        select max(t.score)
        from student_score as t
    )

如果您希望子查询可重用，请尝试使用

select s.score, s.id, m.score
from student_score as s
    cross join (select max(t.score) as score from student_score as t) as m
where s.score = m.score

Answer 3

试试这个：

将您的查询用作子查询，以从实际表中选择分数

select * 
from  student_score 
where score in
 (
    select max(score)
    from   student_score )

Answer 4

Max是一个聚合函数，只返回一行。最简单的方法是发出一个子查询：

SELECT * FROM student_score
WHERE score = (
    SELECT MAX(score) FROM student_score
)

如果你有很多行，请确保你有得分指数。
