如何选出这样的数据？

[fleamboy]

时间 费用 已交 累计欠费
2005-5 20 0 20
2005-6 35 0 55
2005-7 25 80 0
2005-8 20 0 20
2005-9 25 0 45

如何选出欠费的月份数据，就是之中8、9月的两条数据，而不选出5、6月的数据，也就是选出交清费用之后的所有欠费记录！！！！

这样就可以了
create table #a(id int, Year varchar(7),month varchar(5), Money1 money, Money2 money, Money3 money);
insert into #a values(1,'2005','05', 20, 0, 20);
insert into #a values(1,'2005','06', 35, 0, 55);
insert into #a values(1,'2005','07', 25, 80, 0);
insert into #a values(1,'2005','08', 20, 0, 20);
insert into #a values(1,'2005','09', 25, 0, 45);

insert into #a values(3,'2004','09', 25, 0, 75);



select a.id,a.Year,month,money1,money2,money3

drop table #a

select * from tablename where 时间 >(select max(时间 ) from tablename where 累计欠费=0)

[凨叔]

时间应该就是年月吗？是字符串型的？如果是这样，至少应该是yyyy-MM的样式。

create table #a(YearMonth varchar(7), Money1 money, Money2 money, Money3 money);
insert into #a values('2005-05', 20, 0, 20);
insert into #a values('2005-06', 35, 0, 55);
insert into #a values('2005-07', 25, 80, 0);
insert into #a values('2005-08', 20, 0, 20);
insert into #a values('2005-09', 25, 0, 45);

declare @YearMonth varchar(7)
select @YearMonth=MAX(YearMonth) from #a where Money3=0
select * from #a where YearMonth>@YearMonth

drop table #a

结果：
YearMonth Money1 Money2 Money3
--------- --------------------- --------------------- ---------------------
2005-08 20.0000 .0000 20.0000
2005-09 25.0000 .0000 45.0000

[fleamboy]

刚才没有写清楚，我得年月是分开的字符！
年 月 费用 已交 累计欠费
2005 5 20 0 20
2005 6 35 0 55
2005 7 25 80 0

to： jxdjxd1111(qqq)，你这样的话我想如果存在2004年的数据会有问题的啊！

另外如果加入客户信息呢，该如何得到所有用户的欠费信息？

这个结果不是我要得，应为对于客户2来说，在2005-6月交清费用后之前的应该不算欠费了，所有2004年的数据不应该有.
