MSSQL获取昨天，本周，本月。。。

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 <= convert(varchar(10),getdate() + 7,120) and 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()) <= 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
--------------------------------------------------------
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 <= convert(varchar(10),getdate() + 7,120) and 时间字段 >= 时间字段
