mysql获取一个时间段中所有日期或者月份
1:mysql获取时间段所有月份
select date_format(date_add('2020-01-20 00:00:00', interval row month),'%y-%m') date from ( select @row := @row + 1 as row from (select 0 union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) t, (select 0 union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) t2, (select @row:=-1) r ) se where date_format(date_add('2020-01-20 00:00:00', interval row month),'%y-%m') <= date_format('2020-04-02 00:00:00','%y-%m')
2:mysql获取时间段所有日期
select date_add('2020-01-20 00:00:00', interval row day) date from ( select @row := @row + 1 as row from (select 0 union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) t, (select 0 union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) t2, (select @row:=-1) r ) se where date_add('2020-01-20 00:00:00', interval row day) <= '2020-03-02 00:00:00'
备注:
这段代码表示数据条数限制,写两次查询的日期最多显示100条,写三次查询日期最多显示1000次,以此类推,根据你自己的需求决定
下面是设置最多显示条数10000写法
希望能帮助到你,萌新在线求带!!!
下面是其他网友的补充大家可以参考一下
1、不使用存储过程,不使用临时表,不使用循环在mysql中获取一个时间段的全部日期
select a.date from ( select curdate() - interval (a.a + (10 * b.a) + (100 * c.a)) day as date from (select 0 as a union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) as a cross join (select 0 as a union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) as b cross join (select 0 as a union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) as c ) a where a.date between '2017-11-10' and '2017-11-15'
输出如下
date
----------
2017-11-15
2017-11-14
2017-11-13
2017-11-12
2017-11-11
2017-11-10
2、mysql获取两个日期内的所有日期列表
select @num:=@num+1,date_format(adddate('2015-09-01', interval @num day),'%y-%m-%d') as date from btc_user,(select @num:=0) t where adddate('2015-09-01', interval @num day) <= date_format(curdate(),'%y-%m-%d') order by date;
此方法优点就是不需要创建存储过程或者是日历表,缺点就是你必须要有一个表,它的数据条数大到足够支撑你要查询的天数
3、mysql获取给定时间段内的所有日期列表(存储过程)
delimiter $$ drop procedure if exists create_calendar $$ create procedure create_calendar (s_date date, e_date date) begin -- 生成一个日历表 set @createsql = ‘create table if not exists calendar_custom ( `date` date not null, unique key `unique_date` (`date`) using btree )engine=innodb default charset=utf8‘; prepare stmt from @createsql; execute stmt; while s_date <= e_date do insert ignore into calendar_custom values (date(s_date)) ; set s_date = s_date + interval 1 day ; end while ; end$$ delimiter ; -- 生成数据到calendar_custom表2009-01-01~2029-01-01之间的所有日期数据 call create_calendar (‘2009-01-01‘, ‘2029-01-01‘); delimiter $$ drop procedure if exists create_calendar $$ create procedure create_calendar (s_date date, e_date date) begin -- 生成一个日历表 set @createsql = ‘truncate table calendar_custom‘; prepare stmt from @createsql; execute stmt; while s_date <= e_date do insert ignore into calendar_custom values (date(s_date)) ; set s_date = s_date + interval 1 day ; end while ; end$$ delimiter ; -- 生成数据到calendar_custom表2009-01-01~2029-01-01之间的所有日期数据 call create_calendar (‘2009-01-02‘, ‘2009-01-07‘);
