mysql使用存儲過程，創建日歷表：

準備日歷表：

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：

建立日歷表格式：

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_endfrom 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')

最終顯示如下：
