Define a Subpartition in Oracle

Use the Subpartition tab in the Oracle Table Partition Editor dialog to define subpartitions for the selected partitions. You can create subpartitions only for Range, List, and Interval types of partitions. In addition, you can create only Range, List, and Hash types of subpartitions.

When you use the Oracle Table Partition Editor, the constraints that are applied are same as the constraints in an Oracle database. For example, one of the constraints is that you cannot create a partition on a table that is part of a cluster. This constraint applies when you create a partition on an Oracle database therefore it also applies when you use the Oracle Table Partition Editor.

Follow these steps:

Complete the following fields:
Partition Columns--Column
