当天:

select * from T_news where datediff(day,addtime,getdate())=0

最近三天:

select * from T_news where datediff(day,addtime,getdate())<= 2 and datediff(day,addtime,getdate())>= 0

本周:

select * from T_news WHERE (DATEPART(wk, addtime) = DATEPART(wk, GETDATE())) AND (DATEPART(yy, addtime) = DATEPART(yy, GETDATE()))

本月:

select * from T_news WHERE (DATEPART(yy, addtime) = DATEPART(yy, GETDATE())) AND (DATEPART(mm, addtime) = DATEPART(mm, GETDATE()))

最近一个月:

select * from T_news WHERE (DATEPART(yy, addtime) = DATEPART(yy, GETDATE())) 
AND ((DATEPART(mm, addtime) = DATEPART(mm, GETDATE())) OR (31-DATEPART(DD,addtime)+DATEPART(DD, GETDATE()))<=31)

本季度:

select * from T_news where DATEPART(qq, addtime) = DATEPART(qq, GETDATE()) and DATEPART(yy, addtime) = DATEPART(yy, GETDATE())
