我无法更改查询，因为它已经在我们的Oracle Apex应用程序中使用，但最初是视图，我必须将其转换为MV。请提出哪种物化视图适合我的查询，该视图包含32个表以及并集和解析函数。

答案 0 :(得分：0)
不同方法的建议-
您有一个restriction，所以您不能这样做，您必须重写查询以限定条件或使用其他方法。
请避免联合，如果您可以查看是否可以使用联合，请全部使用它 代替。
尝试对发布的每个查询创建多个MV，而不是 您所有的查询都具有分析功能。
那些具有分析功能的人创建它们 作为观看次数
如果要合并，则只需使用sql或创建视图
喜欢
从mv1联合中选择* 从view_1联合中选择* 选择*来自mv2联盟 ....
如果拥有30多个快速刷新MV的海量数据，可能是数据库服务器可能承受着巨大的负担，因此在实施前请先咨询DBA。
