SQLServer中按某字段排列名次

---居然看到有人用游标,SQL就能搞定----

create table Test
(F1 char(10),
F2 char(10))

--测试表

insert into Test
select 'a' F1,'1' F2
union
select 'b' F1,'2' F2
union
select 'c' F1,'3' F2

select 'f' F1,'4' F2
union
select 'g' F1,'4' F2
union
select 'h' F1,'7' F2
union
select 'i' F1,'9' F2

--插入数据

select id=identity(int,0,1),f1,f2 into #t from test order by F2 desc

select a.f1,a.f2,a.id+1-cast(id-cc-minn as Char(10)) as [名次]
from #t a,
(select f2,cc,minn from
(select f2,count()as cc,min(id)-count() as minn from #t group by f2) t)b
where a.f2=b.f2
order by a.f2 desc

--测试

drop table #t
drop table test
