Rewrite To Cube Organized Materialized View Fails With QSM-01284 (Doc ID 756198.1)

Last updated on JULY 09, 2012

Applies to:

Oracle OLAP - Version 11.1.0.6 to 11.2.0.3 [Release 11.1 to 11.2]
Information in this document applies to any platform.
This problem can occur on any platform.

Symptoms

Cube MIT_CUBE is based on ACCOUNTS and RESULTCODES dimensions.
The cube is mapped to ALL_RESULTS table, the dimensions are mapped to ACCOUNTS_DIM and RESULTCODES_DIM tables respectively.

The following query, that refers to the ACCOUNTS_DIM only (it does not refer to the other dimension table) is not rewritten to the cube organized materialized view CB$MIT_CUBE:

SELECT a.account_id, sum(r.count)
        FROM accounts_dim a, all_results r
        WHERE a.account_id = r.account_id
        GROUP BY a.account_id;


DBMS_MVIEW.EXPLAIN_REWRITE (<above_query>, 'CB$MIT_CUBE') gives

QSM-01284: materialized view CB$MIT_CUBE has an anchor table RESULTCODES_DIM not found in query
