关于是时间戳对比的问题
在数据库中,我以时间戳存储数据(time())
现在我要使用如2012/8/22这样的日期去查询
但是遇到一个关于称数的问题
我该如何做才能查到找数据库中等于今天的这个所有数据呢?

------解决方案--------------------
SELECT * FROM tt WHERE FROM_UNIXTIME( time, '%Y/%m/%d' ) ='2012/8/22'
------解决方案--------------------
我建议你将"2012/8/22" 转换成时间戳 比如 N

搜索时间 between N and (N+86400-1)
------解决方案--------------------
$dated = strtotime($_GET['dateitme']);
qsj_magazine.datetime =$dated;
------解决方案--------------------
$dated = strtotime($_GET['dateitme']);
qsj_magazine.datetime =$dated;
------解决方案--------------------
$dated = strtotime($_GET['dateitme']);
qsj_magazine.datetime =$dated;
------解决方案--------------------

PHP code

$oldtime = '2012-8-22 23:59:59';  
$catime = strtotime($oldtime);
SELECT * FROM qsj_user_profile,qsj_magazine WHERE qsj_magazine.uid = qsj_user_profile.uid AND qsj_magazine.datetime > '$catime ';
<br><font color="#e78608">------解决方案--------------------</font><br>我都是将2012/8/22转换成时间戳,需要转换两个值,第一个是2012/8/22这天0点0分,第二个是<br>2012/8/23这天0点0分<br><br>然后再搜索time字段介于上面两个值之间
