Oracle Partitioning offers several partitioning strategies that control how the database places data into partitions. The basic strategies are range, list, and hash partitioning.
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.
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.
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 use a DML MERGE statement to combine INSERT , UPDATE , and DELETE operations for a partitioned table into one statement and perform them atomically.
Right-click the Start menu and select Disk Management. Select the hard disk to create a new partition. Right-click the unpartitioned space in the bottom pane and select New Simple Volume. Enter the size and click Next.
