建立一個數字輔助表

CREATE TABLE `nums` (
  `key` int(11) NOT NULL,
  PRIMARY KEY (`key`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='數字輔助表';

建立一個儲存過程為數字輔助表增加資料

DELIMITER $$
CREATE DEFINER=`root`@`%` PROCEDURE `create_nums`(cnt int unsigned)
BEGIN
declare s int unsigned default 1;
    truncate table nums;
    insert into
 
 nums select s;
    while s*2<=cnt do
        begin
            insert into nums select `key`+s from nums;
            set s=s*2;
        end;
    end while;
END$$
DELIMITER ;

執行儲存過程，增加1-50000進入數字輔助表

call create_nums(50000);

輸入起止日期
SELECT
    @num :[email protected] + 1 AS id,
    date_format(
        adddate(
            '2015-10-2'
 
,
            INTERVAL @num DAY
        ),
        '%Y-%m-%d'
    ) AS date
FROM
    nums,
    (SELECT @num := - 1) t
WHERE
    adddate(
        '2015-10-2',
        INTERVAL @num DAY
    ) < '2016-10-01'
ORDER BY
    date;
