我使用下面的查询来构建物化视图。

ORA-12015：无法从复杂的查询错误消息创建快速刷新物化视图。

我已经为所有表创建了物化视图日志。任何人都可以帮我解决这个问题吗？

Answer 1

CREATE MATERIALIZED VIEW - Restrictions on FAST Refresh

快速刷新的限制

FAST刷新受以下限制：

在创建时指定FAST刷新时，Oracle数据库会进行验证   您正在创建的物化视图符合快速条件   刷新。在ALTER中将刷新方法更改为FAST时   MATERIALIZED VIEW语句，Oracle数据库不执行此操作   验证。如果物化视图不符合快速条件   刷新，然后Oracle数据库在您尝试时返回错误   刷新这个观点。



如果定义，物化视图不符合快速刷新的条件   查询包含分析函数或XMLTable函数。



如果定义，物化视图不符合快速刷新的条件   query引用了一个定义了XMLIndex索引的表。



如果其任何列是，则无法快速刷新实例化视图   加密。

您的查询包含分析结果：

ROW_NUMBER () OVER (PARTITION BY bp_id ORDER BY updtd_dt DESC)

因此您无法对此查询使用快速刷新。
