本周：select * from table where datediff(week,C_CALLTIME,getdate())=0 --C_CALLTIME 为日期字段
本月：select * from table where datediff(Month,C_CALLTIME,getdate())=0 --C_CALLTIME 为日期字段
本季：select * from table where datediff(qq,C_CALLTIME,getdate())=0
求以下日期SQL:
昨天
select convert(varchar(10),getdate() - 1,120)
明天
select convert(varchar(10),getdate() + 1,120)
最近七天
select * from tb where 时间字段 >= convert(varchar(10),getdate() - 7,120)
随后七天
select * from tb where 时间字段 <= convert(varchar(10),getdate() + 7,120) and 时间字段 >= 时间字段
上月
select * from tb where month(时间字段) = month(getdate()) - 1
本月
select * from tb where month(时间字段) = month(getdate())
下月
select * from tb where month(时间字段) = month(getdate()) + 1
如果是在表中查詢:
--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
--随后七天
Select * From TableName Where DateDiff(dd, GetDate(), DateTimCol) <= 7
--上周
Select * From TableName Where DateDiff(wk, DateTimCol, GetDate()) = 1
--本周
Select * From TableName Where DateDiff(wk, DateTimCol, GetDate()) = 0
--下周
Select * From TableName Where DateDiff(wk, GetDate(), DateTimCol ) = 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
