在Navicat中使用触发器每次一直报错1064

想用触发器实现两个表同步增加数据 本来用的测试表 弄成了 让后在作完新表添加触发器 添加不了了 然后我又换的语句也是不行都报错1064 看一下哪个地方出错了
BEGIN
INSERT INTO person(person_number,student_name,student_phone,student_class,student_year) SELECT student_number,student_name,student_phone,student_class,student_year FROM student
WHERE not exists (select * from person where person.person_number = student.student_number);
END

BEGIN
INSERT INTO person (student_number,student_name,student_phone,student_class,student_year)
VALUES (new.student_number,new.student_name,new.student_phone,new.student_class,new.student_year);
END

SQL语法 insert into 表的时候可能哪里写错了，你在检查一下表里面的字段
