各位用户为了找寻关于mysql获取指定时间段中所有日期或月份的语句(不设存储过程，不加表)的资料费劲了很多周折。这里教程网为您整理了关于mysql获取指定时间段中所有日期或月份的语句(不设存储过程，不加表)的相关资料，仅供查阅，以下为您介绍关于mysql获取指定时间段中所有日期或月份的语句(不设存储过程，不加表)的详细内容

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

? 1 2 3 4 5 6 7 8 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

? 1 2 3 4 5 6 7 8 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

? 1 2 3 4 5 6 7 8 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

? 1 2 3 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)

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 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‘);
