Question

我正在尝试将以下数据插入特定表中。似乎没有外键的表允许数据无问题地输入。但是，包含外键的3个表给我以下错误。我不确定自己在做什么错。我所有的PK / FK似乎都正确建立了。制作图表时，我的数据建模者没有表示任何可能的问题。

3个错误：

当我尝试将数据插入到SALES表中时：

从第67行开始的错误- 插入销售（销售编号，零件编号，销售日期，保修日期，零件价格，客户编号，客户编号）价值观（'823'，'4847'，'01/29/18'，'03/29/20'，'250'，'349'，'3495'）错误报告 - ORA-02291：违反完整性约束（TCANNISTRACI.SALES_PARTS_FK）-找不到父密钥

当我尝试将数据插入我的PARTS表中时

从第99行开始的错误-插入零件（零件编号，零件来源，零件编号，零件价格，零件成本，供应商名称，零件说明，零件使用，零件保修日期）值（'2949'，'Supplier'，'2939'，'235'，'49'，'Supplier＃2'，'Lift 零件'，'库存'，'01 / 23/2019'）错误报告-ORA-02291：完整性约束（TCANNISTRACI.PARTS_SUPPLIER_FK）已违反-没有父键找到

当我尝试将数据插入“库存”表时：

错误从第131行开始-插入库存（PartNo，PartPrice，PartQuantity）值（'29384'，'249'，'2'）错误报告-ORA-02291：完整性约束（TCANNISTRACI.INVENTORY_PARTS_FK）已违反-找不到父密钥

Answer 1

您需要更改插入顺序。您应该先将数据插入父表中，以避免违反约束。按以下顺序插入：

客户
供应商
零件
库存
销售

此外，请修复数据以确保外键值匹配并且没有重复的主键。例如，您有唯一键Parts.PartNo的重复值，并且值Part.PartSource与外键Supplier.SupplierNo中的任何条目都不匹配。

Answer 2

我很确定问题在于您的数据类型不同。

parts (partno VARCHAR2(20 CHAR))
sales (partno VARCHAR2(10 CHAR))

您也有带有供应商编号的供应商，但是您要插入带有供应商编号='供应商'的零件

并遵循@chandra插入顺序。

您要插入重复的零件2949。

您的库存零件编号与示例中的part.partno不匹配，而sales.partno也与之不匹配

基本上是一组不一致的数据。我意识到这只是一个例子-但请选择匹配的行！
