SQL获取本周本月本季度的记录的语句

Posted 2020-07-22 BillLei

前提条件：假设表名为：tableName；时间字段名为：theDate

　　①查询本周的记录

　　select * from tableName where DATEPART(wk, theDate) = DATEPART(wk, GETDATE()) and DATEPART(yy, theDate) = DATEPART(yy, GETDATE())

　　②查询本月的记录

　　select * from tableName where DATEPART(mm, theDate) = DATEPART(mm, GETDATE()) and DATEPART(yy, theDate) = DATEPART(yy, GETDATE())

　　③查询本季的记录

　　select * from tableName where DATEPART(qq, theDate) = DATEPART(qq, GETDATE()) and DATEPART(yy, theDate) = DATEPART(yy, GETDATE())

　　select datediff(day,dateadd(mm, datediff(mm,‘‘‘‘,getdate()), ‘‘‘‘),dateadd(mm, datediff(mm,‘‘‘‘,getdate()), ‘‘1900-02-01‘‘))

　　④查询本月记录的通用语句

　　SELECT * FROM [表名] WHERE (DATEPART(mm, 日期) = @month) AND (DATEPART(yy, 日期) = @year)

 

 

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
