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 DEFAULT CHARSET=utf8;

存储过程如下:

CREATE 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:

DROP TABLE
IF
	EXISTS `m_dim_day`;
CREATE TABLE `m_dim_day` (
	`dt` VARCHAR ( 10 ) NOT 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 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')
