非常感谢大家帮忙。。。。。
要统计’200712‘之前的记录就如下了：
declare @year varchar(4) , @month varchar(4)
select @year='2007',@month='12'
select count(1) as total from tab where DATEDIFF(month,[Datetime] ,cast(@year+'-'+@month+'-'+'01' as datetime)) >=0

如果比较到具体的天,就用第一种,如果只比较到月份,就用第二种

----example
create table tab(ID int,Name varchar(10),code varchar(10),[Datetime] datetime)
insert tab
select 1,'aa','aaa','2006-01-05'
union select 2,'bb','bbb','2007-10-12'
union select 2,'bb','bbb','2007-11-12'
union select 2,'bb','bbb','2007-12-12'
union select 2,'bb','bbb','2008-12-12'
declare @year varchar(4) , @month varchar(4)
select @year='2007',@month='12'
select * from tab where DATEDIFF(month,[Datetime] ,cast(@year+'-'+@month+'-'+'01' as datetime)) >=0
drop table tab
/* 结果
ID Name code Datetime
----------- ---------- ---------- ------------------------------------------------------
1 aa aaa 2006-01-05 00:00:00.000
2 bb bbb 2007-10-12 00:00:00.000
2 bb bbb 2007-11-12 00:00:00.000
2 bb bbb 2007-12-12 00:00:00.000

declare @year varchar(4) , @month varchar(4)
select @year='2007',@month='12'
select * from 表table where DATEDIFF(day,[Datetime] ,cast(@year+'-'+@month+'-'+'01' as datetime)) >=0
select @year='2007',@month='12'
select * from 表table where DATEDIFF(day,[Datetime] ,cast(@year+'-'+@month+'-'+'01' as datetime)) >=0

每当传递参数，YEAR,MONTH??
是按这两参数还是当前日期?

select * from tb where convert(varchar(10),日期,120) < convert(varchar(10),getdate(),120)
