我得到这个错误：
错误1452（23000）：无法添加或更新子行：外键约束失败( university . registration ，约束 registration_ibfk_2 外键( section_id )参考文献 Section ( section_id ))
这是我的密码

INSERT INTO Registration VALUES (24766, 1102, 'B', 'B');

CREATE TABLE Registration (
    student_id INT,
    section_id INT,
    midterm_grade VARCHAR(5),
    final_grade VARCHAR(5),
    PRIMARY KEY (student_id, section_id), 
    FOREIGN KEY (student_id) 
        REFERENCES Student (student_id), 
    FOREIGN KEY (section_id) 
        REFERENCES Section (section_id)
);

如能帮助解决此问题，我们将不胜感激。
