日期转换为UNIX时间戳用函数UNIX_TIMESTAMP()

UNIX时间戳转换为日期用函数: FROM_UNIXTIME()

select FROM_UNIXTIME(1156219870);

日期转换为UNIX时间戳用函数: UNIX_TIMESTAMP()

Select UNIX_TIMESTAMP(’2006-11-04 12:23:00′);

例:mysql查询当天的记录数:

$sql=”select * from message Where DATE_FORMAT(FROM_UNIXTIME(chattime),’%Y-%m-%d’) = DATE_FORMAT(NOW(),’%Y-%m-%d’) order by id desc”;

当然大家也可以选择在PHP中进行转换UNIX时间戳转换为日期用函数: date()

date('Y-m-d H:i:s', 1156219870);

日期转换为UNIX时间戳用函数:strtotime()

strtotime('2010-03-24 08:15:42');

实例:

/*

周五 0点至12点 注册医生信息(id,姓名、医院、科室、职称)

*/

select unix_timestamp('2011-09-02 00:00:00'),unix_timestamp('2011-09-02 12:00:00');

select us.uid as 'ID',us.username as '用户名',usf.workunit as '所在医院',usf.jobtitle as '职称',usf.kee as '一级科室',usf.keee as '二级科室',usf.keeee as '三级科室' from uchome_space us,uchome_spacefield usf where us.uid=usf.uid 

and dateline between unix_timestamp('2011-09-02 00:00:00') and unix_timestamp('2011-09-02 12:00:00') and workunit !='' order by dateline desc;
