我正试图使用下面的查询从数据库中删除一个学生记录。但我面对这个错误。

DELETE student, enrolment FROM student INNER JOIN enrolment
WHERE student.stu_nbr=enrolment.stu_nbr and student.stu_nbr = 154;

尝试删除存在注册的学生记录。

delete from student s
where stu_nbr = 154
  and exists (
    select 1
    from enrollment
    where stu_nbr = s.stu_nbr
  );

如果您想从学生表和报名表中删除学生记录，请运行2个查询：

delete from enrollment where stu_nbr = 154;
delete from student where stu_nbr = 154;

如果您想在删除学生时自动删除注册记录，您可能需要查看触发器。
