1、UNIX时间戳转换为日期用函数: FROM_UNIXTIME()
select FROM_UNIXTIME(1156219870);
2、日期转换为UNIX时间戳用函数: UNIX_TIMESTAMP()
Select UNIX_TIMESTAMP('2006-11-04 12:23:00′);
3、日期时间格式函数:DATE_FORMAT()
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;
