MySQL中創建日期維度表

 MySQL中創建日期維度表：

 

CREATE TABLE `dim_day` (
  `DAY_ID` varchar(10) NOT NULL,
  `DAY_SHORT_DESC` varchar(14) DEFAULT NULL,
  `DAY_LONG_DESC` varchar(100) DEFAULT NULL,
	`WEEK_DESC` varchar(20) DEFAULT NULL,
  `WEEK_ID` varchar(100) DEFAULT NULL,
  `WEEK_LONG_DESC` varchar(100) DEFAULT NULL,
  `MONTH_ID` varchar(100) DEFAULT NULL,
  `MONTH_SHORT_DESC` varchar(100) DEFAULT NULL,
  `MONTH_LONG_DESC` varchar(100) DEFAULT NULL,
  `QUARTER_ID` varchar(100) DEFAULT NULL,
  `QUARTER_LONG_DESC` varchar(100) DEFAULT NULL,
  `YEAR_ID` varchar(100) DEFAULT NULL,
  `YEAR_LONG_DESC` varchar(100) DEFAULT NULL,
  PRIMARY KEY (`DAY_ID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

創建過程，參數爲開始日期和創建條數（或者是開始日期和結束日期）：

 

drop procedure if exists f_dim_day;  
create procedure f_dim_day(in start_date VARCHAR(20),in date_count int)
begin  
declare i int;  
set i=0;  
DELETE from dim_day;  
while i < date_count do  
INSERT into dim_day  
(DAY_ID,DAY_SHORT_DESC,DAY_LONG_DESC,WEEK_DESC,WEEK_ID,WEEK_LONG_DESC,MONTH_ID,MONTH_SHORT_DESC,MONTH_LONG_DESC,QUARTER_ID,QUARTER_LONG_DESC,YEAR_ID,YEAR_LONG_DESC)  
SELECT  
REPLACE(start_date,'-','') 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-%m') MONTH_SHORT_DESC,  
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;  
  
call f_dim_day('2019-01-01 00:00:00',DATEDIFF('2020-12-31','2019-01-01')); 

如果是開始日期和結束日期：

 

drop procedure if exists f_dim_day;  
create procedure f_dim_day(in start_date VARCHAR(20),in end_date VARCHAR(20))
begin  
declare i int;  
set i=0;  
DELETE from dim_day;  
while DATE_FORMAT(start_date,'%Y-%m-%d %H:%i:%s') < DATE_FORMAT(end_date,'%Y-%m-%d %H:%i:%s') do  
INSERT into dim_day  
(DAY_ID,DAY_SHORT_DESC,DAY_LONG_DESC,WEEK_DESC,WEEK_ID,WEEK_LONG_DESC,MONTH_ID,MONTH_SHORT_DESC,MONTH_LONG_DESC,QUARTER_ID,QUARTER_LONG_DESC,YEAR_ID,YEAR_LONG_DESC)  
SELECT  
REPLACE(start_date,'-','') 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-%m') MONTH_SHORT_DESC,  
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;  
  
call f_dim_day('2019-01-01 00:00:00','2020-01-01 00:00:00');
