MySql生成日曆表

 

mysql使用存儲過程，創建日曆表：

準備日曆表：

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;

 

 

存儲過程如下：

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

 

 

調用存儲過程如下，參數傳入年份，即生成那一年的數據

call f_m_dim_day('2018'); 

 

 

 

 

 

第二種：

建立日曆表格式：

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;

創建存儲過程：

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

 

調用存儲過程：

 call f_m_dim_day('2018')
