sql求最大，Orz

sflbh           sj      sl
050102      04.00
060101      01.00
050102      74.00
050102      112.00
050102      125.00
050102      132.00
050102      141.00
050102      161.00
060101      161.00
050102      202.00
060101      201.00
050102      234.00

我想根据sflbh求出sl最大值 同时还列出sj列怎么写？
select sflbh,max(sl) from table
group by sflbh 然后需要对应的sj列
[最优解释]

select
  *
from 
  TB t
where
  not exists(select 1 from TB where sflbh=t.sflbh and sl>t.sl)

[其他解释]

--> 测试数据：[TB]
if object_id('[TB]') is not null drop table [TB]
GO
create table [TB]([sflbh] varchar(6),[sj] int,[sl] numeric(3,2))
insert [TB]
select '050102',0,4.00 union all
select '060101',0,1.00 union all
select '050102',7,4.00 union all
select '050102',11,2.00 union all
select '050102',12,5.00 union all
select '050102',13,2.00 union all
select '050102',14,1.00 union all
select '050102',16,1.00 union all
select '060101',16,1.00 union all
select '050102',20,2.00 union all
select '060101',20,1.00 union all
select '050102',23,4.00

select 
     sflbh,
     [sj]=STUFF((SELECT ','+RTRIM(sj) FROM TB WHERE t.[sflbh]=[sflbh] FOR XML PATH('')),1,1,''),
     [sl]=max(sl) from TB t
 group by sflbh


drop table [TB]

[其他解释]

select sflbh,max(sl),sj from 表1 
group by sflbh,sj

我不是把所有的sj全部列出来。我只要列出最大值所对应的sj就可以了

那如果最大值对应那列有几个sj怎么取？取最大还是最小？
------其他解决方案--------------------

select a.sflbh,a.sl,a.sj
from [table] a
inner join
(select sflbh,max(sl) 'maxsl'
 from [table] group by sflbh) b 
on a.sflbh=b.sflbh and a.sl=b.maxsl

[其他解释]
sl 最大值会有一样的，所以显示出来有几笔

select * from TB t where not exists(select 1 from TB where sflbh=t.sflbh and sl>t.sl)

谢谢这办法最好
