mysql - MySQL 错误代码：1452。无法添加或更新子行：外键约束失败

我正在尝试将值插入到员工表中，但是当我尝试执行脚本时，它给了我这个错误。我究竟做错了什么？

回复：

错误代码：1452。无法添加或更新子行：外键约束失败（smolcompany. employee, CONSTRAINT employee_fk2 FOREIGN KEY ( DeptID) REFERENCES department( DeptID) ON DELETE RESTRICT ON UPDATE CASCADE）

行动：

插入员工价值观 (4283, 'Sarim Mansoor', 'M', 27, 'Mont Kiara', NULL, 102), (4465, 'Teh Yi Heng', 'M', 23, 'Cyber​​jaya', NULL, 101 ), (4123, 'Thamal Kishen', 'F', 47, '八打灵再也', 4283, 102), (3978, 'Mike Ross', 'M', 26, 'Mont Kiara', NULL, 103), (5240, '玛莎阿诺德', 'F', 27, 'Mont Kiara', 4465, 101)
