关于不存在的父键的 ORA-02291 错误，而实际上它们确实存在

问题描述 投票：0回答：1

我制作了一个名为 Proprietari 的表，它保存有关某些房地产所有者的信息，这些信息存储在名为 Proprietati 的表中。 我尝试向 Proprietari 表添加值并且它有效。但是，当尝试将值添加到另一个表时，引用预先存储的所有者，会发生以下错误：

命令中从第 94 行开始出错 - INSERT INTO Proprietati VALUES (1,'Apartament 3 comere',75.50,'Bucuresti Sector 3',150000,1112) 错误报告 - ORA-02291: 违反完整性约束 (STANM_49.FK_ID_PROPRIETAR) - 未找到父键

即使我已经添加了具有相应 ID 的所有者。

这就是你声称失败的：

SQL> INSERT INTO Proprietati VALUES (1,'Apartament 3 camere',75.50,'Bucuresti Sector 3',150000,1112);

1 row created.

如您所见，没有错误。

脚本的其余部分也可以正常工作：

SQL> INSERT INTO Proprietati VALUES (2, 'Casa', 150.75, 'Cluj-Napoca', 300000,1112);

1 row created.

SQL> INSERT INTO Proprietati VALUES (3, 'Teren', 500.25, 'Timisoara', 75000,1113);
