Oracle 10g Partition Maintenance Operations (PMOP)

With the 10g release, certain enhanced partition maintenance operations are possible. For a typical partitioned materialized view, the following operations are allowed.

- TRUNCATE PARTITION
- DROP PARTITION
- EXCHANGE PARTITION

Let's see a few examples of these partition operations.

ALTER MATERIALIZED VIEW claims_mv
TRUNCATE PARTITION month_0102;

ALTER MATERIALIZED VIEW claims_mv
DROP PARTITION year_2001;

ALTER MATERIALIZED VIEW claims_mv
EXCHANGE PARTITION year_2001 WITH TABLE sales_2001;

These enhancements avoid the need to execute ALTER TABLE statements directly against the materialized view container table to perform these three PMOPs.
