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.
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.
You can display information about partitioned tables and indexes with Oracle Database views. DBA view displays partitioning information for all partitioned tables in the database. ALL view displays partitioning information for all partitioned tables accessible to the user.
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.
To create and format a new partition (volume) Right-click an unallocated region on your hard disk, and then select New Simple Volume. In the New Simple Volume Wizard, select Next. Enter the size of the volume you want to create in megabytes (MB) or accept the maximum default size, and then select Next.
You can use the ALTER TABLE statement to modify a partitioned table after the table is created. Specifically, you can use the ADD PARTITION clause to add a new data partition to an existing partitioned table.
