mysql创建触发器问题如何解决？

Question

要求：9. 创建触发器，当修改department表中的dept_id时，同步修改emploee表中的dept_id。

这是我写的一直报错

create trigger department_after_insert
after insert on department
for each row
begin 
     update empolyee
     set dept_id=new.dept_id
     where dept_id=new.dept_id
end;

Answer 1

 
create trigger department_after_insert after update 
on department for each row
begin 
     update empolyee
     set dept_id=new.dept_id
     where dept_id=new.dept_id
end;
