mysql獲取指定時間段中所有日期或月份的語句(不設存儲過程，不加表)

更新時間：2021年06月17日 23:44:42 作者：骨力

最近需要用mysql獲取一個時間段中的所有月份，網上查都是要設置存儲過程或者加一個日期表的，不滿足我的需求，翻墻找資料加上自己試驗，如下代碼分享給大家

mysql獲取一個時間段中所有日期或者月份

1：mysql獲取時間段所有月份

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獲取時間段所有日期

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'

備注：

這段代碼表示數據條數限制，寫兩次查詢的日期最多顯示100條，寫三次查詢日期最多顯示1000次，以此類推，根據你自己的需求決定

下面是設置最多顯示條數10000寫法

希望能幫助到你，萌新在線求帶?。?！

下面是其他網友的補充大家可以參考一下

1、不使用存儲過程，不使用臨時表，不使用循環(huán)在Mysql中獲取一個時間段的全部日期

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'

輸出如下

Date
----------
2017-11-15
2017-11-14
2017-11-13
2017-11-12
2017-11-11
2017-11-10

2、mysql獲取兩個日期內的所有日期列表

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;

此方法優(yōu)點就是不需要創(chuàng)建存儲過程或者是日歷表，缺點就是你必須要有一個表，它的數據條數大到足夠支撐你要查詢的天數

3、mysql獲取給定時間段內的所有日期列表(存儲過程)

DELIMITER $$
DROP PROCEDURE IF EXISTS create_calendar $$
CREATE PROCEDURE create_calendar (s_date DATE, e_date DATE)
BEGIN
-- 生成一個日歷表
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$$
DELIMITER ;
-- 生成數據到calendar_custom表2009-01-01~2029-01-01之間的所有日期數據
CALL create_calendar (‘2009-01-01‘, ‘2029-01-01‘);
DELIMITER $$
DROP PROCEDURE IF EXISTS create_calendar $$
CREATE PROCEDURE create_calendar (s_date DATE, e_date DATE)
BEGIN
-- 生成一個日歷表
SET @createSql = ‘truncate TABLE calendar_custom‘;
prepare stmt from @createSql;
execute stmt;
WHILE s_date <= e_date DO
INSERT IGNORE INTO calendar_custom VALUES (DATE(s_date)) ;
SET s_date = s_date + INTERVAL 1 DAY ;
END WHILE ;
END$$
DELIMITER ;
-- 生成數據到calendar_custom表2009-01-01~2029-01-01之間的所有日期數據
CALL create_calendar (‘2009-01-02‘, ‘2009-01-07‘);
