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.
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.
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.
Without partitioning, there is a maximum of 4 294 967 288 rows in a table, or a maximum size of 1.7 TB (where TB equals 1 099 511 627 776 bytes). A partitioned table, however, can have many partitions, with each partition being able to have the maximum table size.
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.
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.
