文档解释

ORA-39805: Parallel loads are not allowed when loading child and parent.

Cause: A parallel load was requested when loading the child and parent of a partitioning referential constraint. This is not allowed.

Action: Remove the parallel option.

ORA-39805 错误是由于在父子表之间尝试并行加载而产生的。它通常由试图将数据从外部数据文件并行加载到包含父子表结构的关系出现。

官方解释

ORA-39805:“将外部数据文件并行加载到具有父子表结构的表时，禁止使用并行加载。”

一般处理方法及步骤

（1）检查要加载的表结构，确保它不包含父子表结构；

（2）如果被加载的表存在父子表结构，请尝试更改加载数据的顺序，先加载父表，然后加载子表；

（3）更改要加载的外部文件的格式，确保它不会在父子表之间出现任何数据冲突。

（4）有时，也可以使用“忽略约束”选项或“多用途表”功能来解决父子表约束问题。
