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。

  1. 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

  2. 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

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
