1、創(chuàng)建一個num表卷雕，用來存儲數(shù)字0~9
CREATE TABLE num (i int);
2节猿、在num表中生成0~9
INSERT INTO num (i) VALUES (0), (1), (2), (3), (4), (5), (6), (7), (8), (9);
3、生成一個存儲日期的表，datalist是字段名
CREATE TABLE if not exists calendar(datelist date);
4滨嘱、生成并插入日期數(shù)據(jù)
INSERT INTO calendar(datelist) SELECT
adddate(
( -- 這里的起始日期峰鄙，你可以換成當(dāng)前日期
DATE_FORMAT("2016-1-1", '%Y-%m-%d')
),
numlist.id
) AS `date`
FROM
(
SELECT
n1.i + n10.i * 10 + n100.i * 100 + n1000.i * 1000+ n10000.i * 10000 AS id
FROM
num n1
CROSS JOIN num AS n10
CROSS JOIN num AS n100
CROSS JOIN num AS n1000
CROSS JOIN num AS n10000
) AS numlist;
5、最后再添加主鍵即可
ALTER TABLE `calendar`
ADD COLUMN `id` int UNSIGNED NOT NULL AUTO_INCREMENT COMMENT '主鍵' FIRST ,
ADD PRIMARY KEY (`id`);
