sql语句得到一天，一周，一月 时间间隔

//当天

(OperateTime >=CONVERT(varchar(10),getDate(),120)+' 00:00:00' and OperateTime <=CONVERT(varchar(10),getDate(),120)+' 23:59:59')

//近三天

DateDiff(day,OperateTime,getdate()) <=3

//本周

sql数据库

 Datepart(year,OperateTime)=DatePart(year,Getdate()) and DatePart(week,OperateTime)=DatePart(week,GetDate())

Access 数据库

Datepart('yyyy',OperateTime)=DatePart('yyyy',date()) and DatePart('ww',OperateTime)=DatePart('ww',Date())

//本月

Datepart(year,OperateTime)=DatePart(year,Getdate()) and DatePart(month,OperateTime)=DatePart(month,GetDate())

OperateTime是表中日期字段
