特别说明下:以下统计本周数据时,星期天是作为下周的第一天,而不是本周最后一天,因此你把星期天作为本周最后一天时,你需要在getDate()的基础上减一天,如dateadd('day', -1, getDate()) 本周:select * from table where datediff(week,C_CALLTIME,getdat

特别说明下:以下统计本周数据时,星期天是作为下周的第一天,而不是本周最后一天,因此你把星期天作为本周最后一天时,你需要在getDate()的基础上减一天,如dateadd('day', -1, 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

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 时间字段 >= 时间字段

convert和dateadd函数结合使用就可以了。

用datediff(day,时间列,getdate())

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())

--随后七天

Select * From TableName Where DateDiff(dd, GetDate(), DateTimCol)

--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

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

1.现在我需要得到只是日期部分,时间部分不要,SQL怎么写?

select convert(varchar(10),getdate(),120)

2.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 时间字段 >= 时间字段
