1.创建表

2.创建存储过程

#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

END AS cycle into dict_value
FROM
weekly_cycle
WHERE

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

group by start_date;
end if;
#插入新的数据
insert into weekly_cycle(cycle,city,start_date,end_date)
SELECT
