  • MySql生成日历表

    mysql使用存储过程,创建日历表:

    准备日历表:

    CREATE TABLE `m_dim_day` (  
      `ID` int(11) NOT NULL AUTO_INCREMENT,
      `DAY_ID` varchar(10) DEFAULT NULL,     
      `DAY_SHORT_DESC` varchar(10) DEFAULT NULL,  
      `DAY_LONG_DESC` varchar(50) DEFAULT NULL,  
      `WEEK_DESC` varchar(20) DEFAULT NULL,  
      `WEEK_ID` varchar(20) DEFAULT NULL,  
      `WEEK_LONG_DESC` varchar(50) DEFAULT NULL,  
      `MONTH_ID` varchar(20) DEFAULT NULL,  
      `MONTH_LONG_DESC` varchar(50) DEFAULT NULL,  
      `QUARTER_ID` varchar(20) DEFAULT NULL,  
      `QUARTER_LONG_DESC` varchar(20) DEFAULT NULL,  
      `YEAR_ID` varchar(20) DEFAULT NULL,  
      `YEAR_LONG_DESC` varchar(50) DEFAULT NULL,  
      PRIMARY KEY (`ID`)  
    ) ENGINE=InnoDB AUTO_INCREMENT=731 DEFAULT CHARSET=utf8;

    存储过程如下:

    CREATE DEFINER=`root`@`localhost` PROCEDURE `f_m_dim_day`(in yr VARCHAR(20))
    begin  
    declare i int;
    declare start_date varchar(20);
    declare end_date varchar(20);
    declare date_count int;
    
        set i=0;  
            set start_date= concat(yr, '-01-01');
            set end_date = concat(yr+1,'-01-01');
        DELETE from m_dim_day where year_id = yr;
            set date_count = datediff(end_date, start_date);
            
        while i < date_count DO  
            INSERT into m_dim_day (DAY_ID,DAY_SHORT_DESC,DAY_LONG_DESC,WEEK_DESC,WEEK_ID,WEEK_LONG_DESC,MONTH_ID,MONTH_LONG_DESC,QUARTER_ID,QUARTER_LONG_DESC,YEAR_ID,YEAR_LONG_DESC)  
                SELECT  
                                DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y%m%d') DAY_ID,  
                    DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y-%m-%d') DAY_SHORT_DESC,  
                    DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y年%m月%d日') DAY_LONG_DESC,  
                    case DAYOFWEEK(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'))  when 1 then '星期日' when 2 then '星期一' when 3 then '星期二' when 4 then '星期三' when 5 then '星期四' when 6 then '星期五' when 7 then '星期六' end WEEK_DESC,  
                    DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y%u') WEEK_ID,  
                    DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y年第%u周') WEEK_LONG_DESC,  
                    DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y%m') MONTH_ID,  
                    DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y年第%m月') MONTH_LONG_DESC,  
                    CONCAT(DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y'),quarter(STR_TO_DATE( start_date,'%Y-%m-%d %H:%i:%s'))) QUARTER_ID,  
                    CONCAT(DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y'),'年第',quarter(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s')),'季度') QUARTER_LONG_DESC,  
                    DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y') YEAR_ID,  
                    DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y年') YEAR_LONG_DESC  
            from dual;  
            set i=i+1;  
            set start_date = DATE_FORMAT(date_add(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),interval 1 day),'%Y-%m-%d');  
        end while;  
    end

    调用存储过程如下,参数传入年份,即生成那一年的数据

    call f_m_dim_day('2018'); 

    第二种:

    建立日历表格式:

    CREATE TABLE `m_dim_day` (
    `dt` varchar(10) DEFAULT NULL,
    `dt2` varchar(10) DEFAULT NULL,
    `yr` varchar(10) DEFAULT NULL,
    `mm` varchar(10) DEFAULT NULL,
    `dd` varchar(10) DEFAULT NULL,
    `dayofweek` varchar(10) DEFAULT NULL,
    `weeknum` varchar(10) DEFAULT NULL,
    `qr` varchar(10) DEFAULT NULL,
    `bourse_week` varchar(10) DEFAULT NULL,
    `yrmm` varchar(10) DEFAULT NULL,
    `week_begin` varchar(10) DEFAULT NULL,
    `week_end` varchar(10) DEFAULT NULL,
    PRIMARY KEY (`dt`)
    )ENGINE=InnoDB AUTO_INCREMENT=1096 DEFAULT CHARSET=utf8;

    创建存储过程:

    CREATE PROCEDURE `f_m_dim_day`(in year VARCHAR(20))
    begin  
    declare i int;
    declare start_date varchar(20);
    declare end_date varchar(20);
    declare date_count int;
    
        set i=0;  
            set start_date= concat(year, '-01-01');
            set end_date = concat(year+1,'-01-01');
        DELETE from m_dim_day where yr = year;
            set date_count = datediff(end_date, start_date);
            
        while i < date_count DO  
            INSERT into m_dim_day (dt,dt2,yr,mm,dd,dayofweek,weeknum,qr,bourse_week,yrmm,week_begin,week_end)  
                SELECT  
                                DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y-%m-%d') dt,  
                                    DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y%m%d') dt2, 
                                    DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y') yr,
                                    DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%m') mm,
                    DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%d') dd,   
                    case DAYOFWEEK(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'))  when 1 then '星期日' when 2 then '星期一' when 3 then '星期二' when 4 then '星期三' when 5 then '星期四' when 6 then '星期五' when 7 then '星期六' end dayofweek,  
                    DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%u') weeknum,  
                                    CONCAT(DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y'),quarter(STR_TO_DATE( start_date,'%Y-%m-%d %H:%i:%s'))) qr,
                    DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y-%u') bourse_week,  
                                    DATE_FORMAT(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),'%Y%m') yrmm,
                    DATE_FORMAT(subdate(start_date,date_format(start_date,'%w')-1),'%Y%m%d') week_begin,
                                  DATE_FORMAT(subdate(start_date,date_format(start_date,'%w')-7),'%Y%m%d') week_end
            from dual;  
            set i=i+1;  
            set start_date = DATE_FORMAT(date_add(STR_TO_DATE(start_date,'%Y-%m-%d %H:%i:%s'),interval 1 day),'%Y-%m-%d');  
        end while;  
    end

    调用存储过程:

     call f_m_dim_day('2018')
