在SQL Server中均根据日期和时间进行排序 [英] Sorting according to date and time both in sql server

问题描述

我有以下查询.vdate和vtime都是表中的varchar字段.

i have the following query.Both vdate and vtime are varchar fields in table.

select (isnull(RTRIM(LTRIM(CONVERT(varchar,convert(datetime,vdate,103),103))),'')+'  '+ isnull(REPLACE(REPLACE(RIGHT('0'+LTRIM(RIGHT(CONVERT(varchar,convert(datetime,vtime,103),100),7)),7),'AM',' AM'),'PM',' PM'),''))
as vdate from table1

它以"08/04/2013 03:00 AM"格式显示vdate列
当我按asc/desc顺序对记录进行排序时，它仅根据日期而不是时间对记录进行排序.我需要根据日期和时间对它们进行排序.我该怎么做?
请帮助..

which displays vdate column in "08/04/2013 03:00 AM" format
when i sort records in asc/desc order it sorts records according to date only and not the time.I need to sort them according to both date and time.How can i do this?
Plz Help..

推荐答案

您是否尝试过这样做

按CAST([日期] AS DATETIME)+ CAST([时间] AS DATETIME)asc

Have you tried doing this

ORDER BY CAST([date] AS DATETIME) + CAST([time] AS DATETIME) asc
