数据库查询显示一年中所有的周一到周五的数据
select * from 表名 where WeekDay(日期字段) -1 between 1 and 5 其中WeekDay是求日期是周几的一个函数,但是按照外国,是从星期日开始算每周的第一天,所以要减去1
select count(*) from weixiuguanli where weixiuzt= '待维修'
select * from weixiuguanli where weixiuzt= '待维修'
select top 5 * from WeiXiuGuanLi Order By baoxiusj Desc --按时间升降
select * from weixiuguanli where baoxiusj >= date() and baoxiusj < DateAdd('d', 1, date()) and weixiuzt='已维修'
select * from weixiuguanli where (DateDiff('d',baoxiusj,Date())=0) -- d 一天
select * from weixiuguanli where (DateDiff('w',baoxiusj,Date())=0) -- w 一7天
select * from weixiuguanli where (DateDiff('m',baoxiusj,Date())=0) -- m 一月
select * from weixiuguanli where (DateDiff('d',baoxiusj,Date())=1) -- d 昨天
select * from weixiuguanli where (DateDiff('q',baoxiusj,Date())=0) -- q 季度
select * from weixiuguanli where (DateDiff('yyyy',baoxiusj,Date())=0) -- y 今年度
select * from weixiuguanli where (DateDiff('yyyy',baoxiusj,Date())=1) -- y 去年度
select * from weixiuguanli where datediff('w',baoxiusj,now()+1)=0 -- w 星期一到星期天
