文档解释

ORA-32334: cannot create prebuilt materialized view on a table already referenced by a MV

Cause: the table on which the materialized view is created as prebuilt is already referenced by a materialized view

Action: create the materialized view on a different table

：

ORA-32334 错误是由于一张表已经被一个MV所引用，而试图在这张表上创建一个预建MV。该错误表明在一张表上，只允许创建一个MV，不允许两个MV同时引用一张表。

官方解释

常见案例

正常处理：在建立MV之前，需要先检查一个表上是否有其他MV，如果有，则必须先删除旧MV，再创建新MV。
