一：带变量
delimiter $$
CREATE PROCEDURE `echarts`()
begin
DECLARE member_count int DEFAULT 0;
SELECT COUNT(id) INTO member_count FROM common_party_member;
delete from common_echarts;
Insert into common_echarts
select case when TIMESTAMPDIFF(YEAR, birthday, CURDATE()) BETWEEN 18 AND 29 then '18-29岁'

when TIMESTAMPDIFF(YEAR, birthday, CURDATE()) > 80 then '80岁以上' end as text,count(id) count,member_count total,ROUND(count(id)/member_count*100,1) percent,'age' type from common_party_member GROUP BY text
union
select education text,count(id) count,member_count total,ROUND(count(id)/member_count*100,1) percent,'education' type
from common_party_member GROUP BY text
end
delimiter;
二：带输入参数
delimiter $$
