ORA-32332: cannot refresh materialized view “string”.”string” as type evolution has occured

文档解释

ORA-32332: cannot refresh materialized view “string”.”string” as type evolution has occured

Cause: The types used by the materialized view or its master tables have been evolved.

Action: Ensure that the types used by the materialized view have been evolved to the same version at both the master and materialized sites. Then, before refreshing the materialized view, evolve the materialized view using ALTER MATERIALIZED VIEW.

这个错误指的是，用户尝试使用 REFRESH MATERIALIZED VIEW 语句来刷新一个已修改的物化视图，而该操作被拒绝。

官方解释

常见案例

一般处理方法及步骤

1.首先在语句 REFRESH MATERIALIZED VIEW 中指定 ALTER 关键字，表明允许 Oracle 对物化视图进行类型演变。

2.使用 ALTER MATERIALIZED VIEW 语句确保物化视图和底层表保持一致。

3.使用 REFRESH MATERIALIZED VIEW 语句以刷新物化视图数据。
