Oracle Error Message
ORA-12030: cannot create a fast refresh materialized view
Reason for the Error
The materialized view log did not exist or did not log the information needed by the materialized view to perform a fast refresh.
Solution
Ensure that the materialized view log exists and logs the necessary information.
– For ROWID materialized views, the master table’s ROWID must be logged.
– For primary key materialized views, the master table’s primary key columns must be logged.
– For subquery materialized views, the filter columns, primary key, and ROWID values must be logged.
– For object materialized views, object id must be logged.
