各位大侠帮忙了，这个sql怎么写

[zxq68677511]

有表：
id name score
1 '张' 88
2 '张' 90
3 '王' 80
4 '王' 78
求：每个name中score最高的id,结果应该是：2--90；3--80
问：这个sql怎么写？急！

[wangdehao]

select * from tb a
where not exists(
select * from tb
where name=a.name and score>a. score
)

----or:

select * from tb a inner join
(select name,score=max(score)
from tb group by name) b
on a.name = b.name and a.score=b.score

[vinsonshen]

select * from 表名 as a where not exists (select * from 表名 where name=a.name and score >a.score)
