mysql 的 触发器

建了3个触发器

1

create trigger t before insert on books for each row  set new.name = 'aaaddd'   2 create trigger t3 after delete on books for each row delete from a_student where sid=old.id

3

create trigger t2 before insert on a_student for each row  begin insert into books values (new.sid,new.name);

end

加begin end 就报错 Sql state 42000   error code 1064 去掉 begin end 不报错了   怎么回事

 

看了mysql5.1的中文官方文档  应该这么写 注意蓝色部分

end
