mysql 时间间隔查询

select count(*) from sometable where datetimecolumn>=UNIX_TIMESTAMP('2010-03-01 00:00:00') and datetimecolumn

你表中的数据,根据你的题目,应该是全部显示才对。是小于5秒还是5分钟? 下面这个是 两条数据间小于5秒的记录的查询语句 select *,timestampdiff(second,t1.time,(select time from table3 where t1.idid order by id desc limit 1),t1.time ) ...

select timestampdiff(minute,"2016-08-09 11:15:16","2016-08-09 11:55:16");

select * from table where 时间字段 between '2010-7-12 11:18:54' and '2010-7-12 11:22:20'

TIMESTAMPDIFF(interval,datetime_expr1,datetime_expr2) www.2cto.com 说明: 返回日期或日期时间表达式datetime_expr1 和datetime_expr2the 之间的整数差。其结果的 单位由interval 参数给出。interval 的法定值同TIMESTAMPADD()函数说明中所列...

SELECT * FROM `tbl` WHERE id IN ( SELECT MAX(id) FROM `tbl` WHERE createdat BETWEEN ADDDATE(DATE_FORMAT(NOW() ,"%Y-%m-%d"), INTERVAL -6 DAY) AND DATE_FORMAT(NOW(),'%Y-%m-%d') GROUP BY DATE_FORMAT(createdat,'%Y-%m-%d') ) 前提你...

select dtime,name from(select name,dtime,rank,ptime,ptime2 from(select cg_tmp.*, @rownum :=@rownum + 1,if(TIMESTAMPDIFF(MINUTE, @ptime,cg_tmp.dtime)

用时间戳来计算 SELECT (UNIX_TIMESTAMP(NOW())-UNIX_TIMESTAMP('2015-04-20 15:12:12'))/60;也就是得到两个时间相差的秒数,然后除60得到分种。

mysql常用的日期加减函数与实例教程 MySQL 日期类型 MySQL 日期类型:日期格式、所占存储空间、日期范围 比较。 日期类型 存储空间 日期格式 日期范围 ------------ --------- --------------------- -----------------------------------------...

SELECT DATE_FORMAT(time,'%Y-%m-%d') as day, sum(case when amount>0 then amount when amount=0 then 0 end) as amount1 from table where time>='2014-11-01' group by day; 我没有测试。time表示日期,amount表示数量。查询11月后每天成交数量
