select * from tb where datediff(week , 时间字段 ,getdate()) = 0
上周
select * from tb where datediff(week , 时间字段 ,getdate()) = 1
下周
select * from tb where datediff(week , 时间字段 ,getdate()) = -1
----------------------------------------------------------------------------------------

--上月
Select * from TableName Where DateDiff(mm, DateTimCol, GetDate()) = 1
--本月
Select * from TableName Where DateDiff(mm, DateTimCol, GetDate()) = 0
--下月
Select * from TableName Where DateDiff(mm, GetDate(), DateTimCol ) = 1
昨天：dateadd(day,-1,getdate())
明天：dateadd(day,1,getdate())
上月：month(dateadd(month, -1, getdate()))
本月：month(getdate())
下月：month(dateadd(month, 1, getdate()))
---------------------------------------------------------------------------------
--昨天
Select * from TableName Where DateDiff(dd, DateTimCol, GetDate()) = 1
--明天
Select * from TableName Where DateDiff(dd, GetDate(), DateTimCol) = 1
--最近七天
Select * from TableName Where DateDiff(dd, DateTimCol, GetDate()) <= 7
