Insufficient key column information for updating and refreshing
For more complicated filters (such as those involving disjunctions) you will have to create a new view in the database, or use a stored procedure.
Oracle Database can use this materialized view log to perform fast refreshes for all fast-refreshable materialized views based on the master table.
You can pass in the instance of your class as an argument to the proc. For example: Here is an example class that uses an instance method to determines the encryption key to use.
All of the aforementioned options are explained in depth below.
To fast refresh a materialized join view, you must create a materialized view log for each of the tables referenced by the materialized view.
, then Oracle Database assumes the master table is contained in your own schema.
