Fast Refresh using two non-primary key tables
I have a materialized view based on two tables with an outer join clause. Both the tables do not have a primary key so I had created materialized view log with row-id on each of them but still I am not able to bring out the fast refresh option for the materialized view. My question is can I have a fast refresh option for materialized view built from two tables without primary keys and having an outer join clause????. If possible please send me some sample scripts for quicker understanding.
Thanks and Regards,
