ORA-12351: cannot create view using a remote object which has a remote object reference

文档解释

ORA-12351: cannot create view using a remote object which has a remote object reference

Cause: You tried to create a view which references a remote object which, in turn, references an object on another database. Since the view that you tried to create references a remote object, that object cannot reference an object on another database.

Action: Choose a different object to reference in your view or change the remote object so that it does not reference another database.

这个错误指出不可以使用远程对象来创建视图，官方解释是你不可以使用远程对象来创建视图。这是因为Oracle的数据库引擎不允许使用远程对象来创建视图。

常见案例是当用户尝试创建视图时，查询使用了远程对象表、远程视图或远程函数的情况下。

正常处理方法及步骤

1. 确认查询是否使用了远程对象表、远程视图或远程函数。

2. 对查询中的远程对象重新进行定义。

3. 重新定义远程对象后，再次尝试创建视图。
