Sql Server中查询今天、昨天、本周、上周、本月、上月数据
在做Sql Server开发的时候有时需要获取表中今天、昨天、本周、上周、本月、上月等数据,这时候就需要使用DATEDIFF()函数及GetDate()函数了。 DATEDIFF ( datepart , startdate , enddate ) 释义:计算时间差 datepare值:year | quarter | month | week | day | hour | minute | second | millisecond startdate:开始日期 enddate :结束日期 GetDate() 释义:获取当前的系统日期
下面例子中表名为tablename,条件字段名为inputdate
下面例子中表名为tablename,条件字段名为inputdate
查询今天SELECT * FROM tablename where DATEDIFF(day,inputdate,GETDATE())=0
查询昨天SELECT * FROM tablename where DATEDIFF(day,inputdate,GETDATE())=1
查询本周SELECT * FROM tablename where datediff(week,inputdate,getdate())=0
查询上周SELECT * FROM tablename where datediff(week,inputdate,getdate())=1
查询本月SELECT * FROM tablename where DATEDIFF(month,inputdate,GETDATE())=0
查询上月SELECT * FROM tablename where DATEDIFF(month,inputdate,GETDATE())=1
