1.创建表

DROP TABLE IF EXISTS `weekly_cycle`;
CREATE TABLE `weekly_cycle`  (

-- ----------------------------

DROP TABLE IF EXISTS `weekly_target_amount`;
CREATE TABLE `weekly_target_amount`  (

2.创建存储过程

CREATE DEFINER=`root`@`%` PROCEDURE `pro_test`(in count int(11))
begin
declare temp int default 0;
declare dict_value int ;
declare month_str int;

#初始化month
  select date_format( start_date, '%m' ) into  month_str from weekly_cycle
    where start_date= ( SELECT max( start_date ) FROM weekly_cycle ) 
    group by start_date;

#循环插入weekly_cycle
while temp < count DO

#计算dict_value初始值
SELECT
CASE
WHEN
    locate( '一', cycle ) THEN
    2 
    WHEN locate( '二', cycle ) THEN
    3 
    WHEN locate( '三', cycle ) THEN
    4 
    WHEN locate( '四', cycle ) THEN
    1 
    END AS cycle into dict_value
FROM
    weekly_cycle 
WHERE
    end_date = ( SELECT max( end_date ) FROM weekly_cycle ) 
GROUP BY
    cycle;

#计算月份
if dict_value = 1 then
  select (date_format( start_date, '%m' )+1) into  month_str from weekly_cycle
    where start_date= ( SELECT max( start_date ) FROM weekly_cycle ) 
    group by start_date;

end if;

#插入新的数据
insert into weekly_cycle(cycle,city,start_date,end_date) 
SELECT
    concat(
    date_format( cycle.new_start_date, '%Y' ),
    '年',
     month_str,
    '月',
    ( SELECT NAME FROM weekly_dict WHERE type = 'proc' AND VALUE = dict_value ) 
    ) AS cycle,
    city.union_name as city,
    cycle.new_start_date AS start_date,
    cycle.new_end_date AS end_date 
FROM
    ( SELECT DISTINCT union_name FROM weekly_target_amount ) AS city,
    (
SELECT
    date_add( new_weekly_cycle.end_date, INTERVAL 1 DAY ) AS new_start_date,
    date_add( new_weekly_cycle.end_date, INTERVAL 7 DAY ) AS new_end_date 
FROM
    ( SELECT max( start_date ) AS start_date, max( end_date ) AS end_date FROM weekly_cycle ) AS new_weekly_cycle 
    ) AS cycle;

/*

#参数重置循环
if (dict_value = 4) then 
    set dict_value = 1;
end if;
set dict_value = dict_value + 1; */
#重置循环
set temp = temp + 1;
end while;#结束while循环
end
