Range partitioning is a convenient method for partitioning historical data. The boundaries of range partitions define the ordering of the partitions in the tables or indexes. Interval partitioning is an extension to range partitioning in which, beyond a point in time, partitions are defined by an interval.
You cannot explicitly add a partition to an interval-partitioned table. The database automatically creates a partition for an interval when data for that interval is inserted.
Composite partitioning is a combination of the basic data distribution methods; a table is partitioned by one data distribution method and then each partition is further subdivided into subpartitions using a second data distribution method.
Use the ALTER TABLE ADD PARTITION statement to add a new partition to the "high" end (the point after the last existing partition). To add a partition at the beginning or in the middle of a table, use the SPLIT PARTITION clause.
To create a composite partitioned table, you start by using the PARTITION BY RANGE | LIST clause of a CREATE TABLE statement. Next, you specify a SUBPARTITION BY RANGE | LIST | HASH clause that follows similar syntax and rules as the PARTITION BY RANGE | LIST | HASH clause.
2.1 Partitioning Overview. Partitioning provides a technique to subdivide objects into smaller pieces. Partitioning allows a table, index, or index-organized table to be subdivided into smaller pieces, where each piece of such a database object is called a partition.
You cannot explicitly add a partition to an interval-partitioned table. The database automatically creates a partition for an interval when data for that interval is inserted.
Subpartitioning—also known as composite partitioning—is the further division of each partition in a partitioned table.
ORA-14097: column type or size mismatch in ALTER TABLE EXCHANGE PARTITION Cause: The corresponding columns in the tables specified in the ALTER TABLE EXCHANGE PARTITION are of different type or size Action: Ensure that the two tables have the same number of columns with the same type and size.
