[解决办法]
select a.name,Count=max(a.count)
from 表1 a inner join 表2 b
on a.name=b.name
group by a.name
order by a.name
[解决办法]
select a.Name,(select max(Count) from 表1 where name=a.name)[count] from 表2 a
[解决办法]
Select
B.Name,
Max(A.[Count]) As [Count]
From
表2 B
Inner Join
表1A
On A.Name = B.Name
Group By B.Name
