mysql面向过程学习

见鬼了，运行的时候就会出问题，什么栈内存不足，我是mac，要改/Etc/my.cnf, 改成256k就够了，直接用vsc编辑器打开吧，vi打开权限不够，改东西还要去查命令行，烦，

然后我tm重启半天，命令行反正我没搞好，直接去偏好设置那里停止，然后启动mysql吧。真坑

create table People(
    id int not null auto_increment,
    name varchar(20),
    age int,
    birthday datetime,
        primary key(id)
)ENGINE=InnoDB DEFAULT CHARSET=utf8;
alter table People modify id  auto_increment;
insert into People(name,age,birthday) values('Amanda','1',CURRENT_DATE());
insert into People(id,name,age,birthday) values(2,'Balea',18,CURRENT_DATE());

create procedure GetPeopleName()
begin
    select name from People;
end;
--执行
call GetPeopleName();
