ORA-24051: cannot propagate object type payloads that have a REF attribute

文档解释

ORA-24051: cannot propagate object type payloads that have a REF attribute

Cause: An ADD_SUBSCRIBER or ENQUEUE procedure with a non-NULL address field in the agent type was issued on a queue whose payload has a REF attribute. Propagation of object type payloads that have a REF attribute currently is not supported.

Action: Specify an agent with a NULL address field so that the agent can dequeue from the same queue. Or, change the object type definition to one that does not use REF attributes.

ORA-24051 是一种由ORACLE数据库引发的错误，它指出不能传播具有REF属性的对象类型有效载荷。REF属性表示一种特殊的引用，可以引用对象的属性或者对象的方法之一。

官方解释

常见案例

一般处理方法及步骤

1.检查引发此错误的对象类型有效载荷，确认其是否具有REF属性。

2.检查执行UPDATE或DELETE操作时，传播的对象类型有效载荷是否具有REF属性。

3.如果执行的操作传播的对象类型有效载荷具有REF属性，则在不修改程序的情况下，可以使用属性传播的别名来解决问题。

4.如果引发此错误的对象类型有效载荷不具有REF属性，则应检查尝试使用的语句是否正确，并重新检查以确保语句的正确性。
