在SQL Server中的两个日期之间以及从单列或双列中检索数据

问题描述

亲爱的所有人，

我有两个varchar数据类型字段来存储简单日期.我知道没有一种在varchar中存储日期的好方法，但是由于某种错误，它占用了它，现在插入了很多数据.

我有2列，例如1. From date和2.迄今为止

如果我有类似
的数据
起始日期|迄今为止
----------------------------------
1. 2012/08/06 2012/08/06
2. 2012/08/06 2012/08/09
3. 2012/08/05 2012/08/09


如果执行此日期与2012/08/06和2012/08/06的查询，我想要的两个结果像1和2，因为第二个包含相同的日期.迄今为止仍然相同.

所以，我该怎么做到..

我使用但未获得完美结果....

Dear All,

I have two fields of varchar datatype to store the simple date. i know there is not good way to store date in varchar but by some mistake it taken it and lots of data inserted now.

I have 2 column like 1. From date and 2 . To date

if i have data like

From Date | To Date
----------------------------------
1. 2012/08/06 2012/08/06
2. 2012/08/06 2012/08/09
3. 2012/08/05 2012/08/09


if execute the query with 2012/08/06 and 2012/08/06 this dates, the two result i want to come like 1 and 2 because the second one containt the same date. ans same for to date.

so, how can i achive this ..

推荐答案

select leave_id,date_of_leave,from_name,dept,from_date,to_date,total_days,reason,report_to_whom
from leave_record
inner join empl on leave_record.from_name=empl.name
where convert(datetime,convert(varchar(10),leave_Record.date_of_leave,102)) between '2012/08/06' and '2012/08/09' order by convert(datetime,convert(varchar(10),leave_record.from_date,102)) desc
