------解决方案--------------------
还是没猜出来,看看是不是这个:
if object_id('tb') is not null drop table tb
go
create table tb([id] int,[开始时间] datetime,[过期时间] datetime)
insert tb select 1,'2008-11-05','2008-12-05'
union all select 2,'2008-11-09','2009-10-17'
union all select 3,'2008-11-12','2008-12-18'
union all select 4,'2008-11-18','2009-06-08'
go
select * from tb order by datediff(dd,开始时间,过期时间) desc
/*
id 开始时间 过期时间

id 开始时间 过期时间

2 2008-11-09 2009-10-17
3 2008-11-12 2008-12-18
1 2008-11-05 2008-12-05
是不是ID先偶后奇,开始时间DESC,国旗时间DESC??

--是不是先过期的后未过期的,然后按天数
if object_id('tb') is not null drop table tb
go
create table tb([id] int,[开始时间] datetime,[过期时间] datetime)
insert tb select 1,'2008-11-05','2008-12-05'
union all select 2,'2008-11-09','2009-10-17'
union all select 3,'2008-11-12','2008-12-18'
union all select 4,'2008-11-18','2009-06-08'
go
SELECT * FROM tb ORDER BY CASE WHEN DATEDIFF(DD,[过期时间],GETDATE()) < 0 THEN 0 ELSE 1 END,
ABS(DATEDIFF(DD,[过期时间],GETDATE()))
