Is it possible to partially refresh a materialized view in Oracle?

Question

I have a very complex Oracle view based on other materialized views, regular views as well as some tables (I can\'t \"fast refresh\" it). Most of the time, existing records

Answer 1

Partition by date as in answer 3 (skaffman).

You could just do the refresh of a normal mv(table_refreshed below) and than use the exchange keyword i.e.

ALTER TABLE all_partitions
  EXCHANGE PARTITION to_calculate
  WITH TABLE table_refreshed
  WITHOUT VALIDATION
  UPDATE GLOBAL INDEXES;
