How do I add an interval partition to an existing table in Oracle?

You cannot partition an existing non-partitioned table. In general, you’ll need to create a new partitioned table, move the data from the existing table to the new table (probably using a direct-path insert with parallel DML), drop the old table, and rename the new table to use the old name.

How do you check whether the table is partitioned or not in Oracle?
