我不明白为什么我有这个错误，尤其是来自guest表的那个错误，表示未找到完整性约束父键

2 个答案:

答案 0 :(得分：2)

我肯定不会查看您发布的每一行，因为您的第一个insert语句中的错误可能会对以下insert语句产生级联效应

但是，如果我使用以下insert语句专注于您的第一个错误：

INSERT INTO Guest VALUES ('G001', 'Genos Kouhai', 'genos@hero.com', 'H003', 'RM301', 'B000000003')

...看起来您已将house_id和room_no值反转。

为了避免这种错误，如果您在insert语句中明确命名列，那会更好。例如：

insert into my_table (col1, col2, col3) values ('val1', 'val2', 'val3')

...哦，小方注意：不要被这些完整性约束错误所困扰。相反，请感谢它阻止您完全破坏您的数据。

答案 1 :(得分：0)

下面：

INSERT INTO Guest VALUES ('G001', 'Genos Kouhai', 'genos@hero.com',
           'H003', 'RM301', 'B000000003');

您正在尝试插入House表中不存在的house_id ='RM301'。
因为Geust表中定义了外键：

CREATE TABLE Guest (
..... ,
    FOREIGN KEY (House_ID)
    REFERENCES House (House_ID),
....);

您收到ORA-02291错误。
