Why does a ORA-12054 error occur when creating this simple materialized view example?

Question

ALTER TABLE RECORDINGS ADD PRIMARY KEY (ID);

CREATE MATERIALIZED VIEW LOG ON RECORDINGS TABLESPACE USERS NOLOGGING;

DROP MATERIALIZED VIEW REC_SEARCH_TEST;
CREATE          


        

Answer 1

The important thing to note about the question is that it is not about fast refresh, but complete refresh. Thus, there is no logical reason that the usual restrictions for fast refresh on commit should apply, except the one that all referenced objects must be local.

The "refresh complete on commit is a relatively new feature, so the best answer to the "why" question is probably "Oracle has not yet implemented this fully, please check future versions of Oracle Database". Not very useful, but true...
