有一张表

CREATE TABLE geography_schedule(   id int(10)UNSIGNED NOT NULL,   geography_address_id int(10)UNSIGNED NOT NULL,   geography_city_id int(10)UNSIGNED NOT NULL,   sort int(5)UNSIGNED NOT NULL DEFAULT'500',   site varchar(5)NOT NULL DEFAULT'site',   group_id int(10)NOT NULL DEFAULT'0',   day int(10)NOT NULL DEFAULT'1',   all_day tinyint(2)NOT NULL DEFAULT'0',   freeday int(10)NOT NULL DEFAULT'0',   from varchar(5)NOT NULL DEFAULT '09:00',   to varchar(5)NOT NULL DEFAULT '18:00',   timestamp时间戳NOT NULL DEFAULT CURRENT_TIMESTAMP,   timestamp_update时间戳NOT NULL DEFAULT CURRENT_TIMESTAMP )ENGINE = InnoDB DEFAULT CHARSET = utf8;

INSERT INTO geography_schedulefromtogeography_address_idday_fromday_togroup_id)价值观 ('09:00','18:00',533,1,1,1), ('09:00','18:00',533,2,2,1), ('11:00','17:00',533,3,3,1), ('11:00','17:00',533,4,4,1), ('09:00','18:00',533,5,5,1), ('10:00','17:00',533,6,6,1), ('09:00','18:00',533,7,7,1;)

我在这个表enter image description here

中有一个mysql查询
SELECT `from`,`to`, `geography_address_id`, MIN(`day`) as `day_from`
 ,MAX(`day`)  as  `day_to`,`group_id`  
FROM `geography_schedule` 
WHERE `geography_address_id` = 533 
GROUP BY `from`,`to` 
ORDER BY `geography_schedule`.`day` ASC

结果:

current result

我需要按行分组9:00 - 18:00以节省日期day_from& day_to按正确顺序排列。

是否可以以这样的方式使用GROUP BY,它会给出这样的结果?
