on 8.1.7 I have the following error :
ORA-12032: cannot use rowid column from materialized view log on "string"."string"
The solution is :
Action: A complete refresh is required before the next fast refresh. Add ROWID columns to the materialized view log, if required.
How can I do a complete refresh before the next fast refresh or Add ROWID columns ? How to know if Add ROWID columns is required ?
