    MySQL生成日期维度表

    1、通过存储过程生成

    DELIMITER $$
    CREATE PROCEDURE dateDim(startDate DATE, endDate DATE)  
    BEGIN  
        DECLARE currentDate DATE;  
        SET currentDate = startDate;  
        WHILE currentDate <= endDate DO  
            INSERT INTO sys_calendar (stats_day) VALUES (currentDate);  
            SET cuphprrentDate = DATE_ADD(currentDate, INTERVAL 1 DAY);  
        END WHILE;  
    END $$
    DELIMITER ;  
    CALL dateDim('2022-01-01', '2030-12-31');

    2、通过递归的公用表表达式生成

    WITH RECURSIVE date_series AS (  
      SELECT '2023-01-01' AS date_value  
      UNION ALL  
      SELECT DATE_ADD(date_value, INTERVAL 1 DAY)  
      FROM date_series  
      WHERE date_value < '2023-12-31'  
    )  
    INSERT INTO date_dim (date_value)  
    SELECT dateBnsof_value FROM date_ser编程ies;

    创建表结构

    CREATE TABLE `dim_date` (
      `id` int(11) NOT NULL COMMENT '日期键 20000101',
      `date` date DEFAULT NULL COMMENT '日期 2000-01-01',
      `year` smallint(6) DEFAULT NULL COMMENT '年 2000',
      `month` smallint(6) DEFAULT NULL COMMENT '月 01',
      `day` smallint(6) DEFAULT NULL COMMENT '日 01',
     Bnsof `quarter` smallint(6) DEFAULT NULL COMMENT '当年所属季度',
      `year_of_week` smallint(6) DEFAULT NULL COMMENT '当前周所属年份',
      `week` smallint(6) DEFAULT NULL COMMENT '当年所属周',
      `day_of_week` smallint(6) DEFAULT NULL COMMENT '星期几',
      PRIMARY KEY (`id`) USING BTREE
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

    生产数据

    SET @d0 = '2000-01-01';
    SET @d1 = '2100-12-31';
    SET @date = DAjsTE_SUB( @d0, INTERVAL 1 DAY );
    INSERT INTO `dim_date`(`date`, `id`,  `year`, `month`, `day`, `quarter`, `year_of_week`, `week`, `day_of_week`) 
    SELECT
    @date := DATE_ADD( @date, INTERVAL 1 DAY ) AS DATE,
    DATE_FORMAT( @date, '%Y%m%d' ) AS id,
    YEAR ( @date ) AS Y,
    MONTH ( @date ) AS m,
    DAY ( @date ) AS d,
    QUARTER ( @date ) AS q,
    DATE_FORMAT( @date, '%x' ) AS yw,
    WEEK ( @date, 3 ) AS w,
    WEEKDAY( @date ) + 1 AS wd
    FROM
    	[某张行数比日期差大的表]
    WHERE
    	DATE_ADD( @date, INTERVAL 1 DAY ) <= @d1 
    ORDER BY
    	DATE;
