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)
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) awhere a.Date between ’2017-11-10’ and ’2017-11-15’
輸出如下
Date----------2017-11-152017-11-142017-11-132017-11-122017-11-112017-11-10
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 datefrom btc_user,(select @num:=0) t where adddate(’2015-09-01’, INTERVAL @num DAY) <= date_format(curdate(),’%Y-%m-%d’)order by date;
此方法優點就是不需要創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 DOINSERT 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 $$CREATE PROCEDURE create_calendar (s_date DATE, e_date DATE)BEGIN-- 生成一個日歷表SET @createSql = ‘truncate TABLE calendar_custom‘;prepare stmt from @createSql;execute stmt;WHILE s_date <= e_date DOINSERT IGNORE INTO calendar_custom VALUES (DATE(s_date)) ;SET s_date = s_date + INTERVAL 1 DAY ;END WHILE ;END$$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‘);
