以下代码中times为时间字段,类型为datetime

1.查询大于times十五分钟的数据

//大于号后面都是获取times十五分钟后的时间
select*from table where now() >SUBDATE(times,interval -15 minute);
select*from table where now() > SUBDATE(times,interval -900 second);
select*from table where now() > date_add(times,interval 15 minute);
select*from table where now() >ADDDATE(times,interval 15 minute);

2.查询大于times一小时的数据

//大于号后面都是获取times一小时后的时间
select*from table where now() >SUBDATE(times,interval -1 hour);
select*from table where now() > SUBDATE(times,interval -60*60 second);
select*from table where now() > date_add(times,interval -1 hour);
select*from table where now() >ADDDATE(times,interval 15 hour);

3.查询大于times一天的数据

//大于号后面都是获取times一天后的时间
select*from table where now() >SUBDATE(times,interval -1 day);
select*from table where now() > SUBDATE(times,interval -60*60*60 second);
select*from table where now() > date_add(times,interval -1 day);
select*from table where now() >ADDDATE(times,interval 15 day);

相应的如果想查询前一天的数据,加一个“-”号即可
