创建一个定时器，实现以下功能

定时器要求：

1. 定时执行某存储过程，存储过程实现向某表中插入一条数据
2. 每分钟执行一次

show variables like '%event_scheduler%';
set global event_scheduler=on;

create table user01(
  user_id int ,
  user_name varchar(3)
);

create procedure shijhian()
begin
 declare i int default 0;
 declare user_id int default 0;
 declare user_name VARCHAR(5) ;
 while i<1 do
 set user_id=i;
 set user_name=concat('我',i);
 insert into user01() value (user_id,user_name);
 set i=i+1;
 end while;
end;

create event e_minute
on schedule every 1 minute
do call shijhian();

select * from user01
