SQLServer 查询最近一天,三天,一周,一月,一季度数据的方法

三天 select * from T_news where datediff(day,addtime,getdate())<= 2 and datediff(day,addtime,getdate())>= 0

一周 select * from T_news WHERE (DATEPART(wk, addtime) = DATEPART(wk, GETDATE())) AND (DATEPART(yy, addtime) = DATEPART(yy, GETDATE()))
注意:此时不能用 datediff 差值为7,因为,datediff只表示间隔数
一月 select * from T_news WHERE (DATEPART(yy, addtime) = DATEPART(yy, GETDATE())) AND (DATEPART(mm, addtime) = DATEPART(mm, GETDATE()))
一季度 select * from T_news where DATEPART(qq, addtime) = DATEPART(qq, GETDATE()) and DATEPART(yy, addtime) = DATEPART(yy, GETDATE())
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
前半年1-6,后半年7-12:select * from table where datepart(mm,C_CALLTIME)/7 = datepart(mm,getdate())/7
 

sql得到当前系统时间得 日期部分

CONVERT(varchar(10),getDate(),120)

 

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

--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

--------------------------------------------------------

本周

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
