第一步，创建函数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 idate_count do INSERT into dim_day (DAY_ID,DAY_SHORT_DESC,DAY_LONG_DESC,WEEK_ID,WEEK
第一步，创建函数 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
INSERT into dim_day
(DAY_ID,DAY_SHORT_DESC,DAY_LONG_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,
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;
第二步，调用函数传入开始时间和天数 ，执行如下sql：
call f_dim_day(‘2015-01-01’,365)
生成效果如下：
![]()
