Is this for the initial creation of the partitioned table? If yes, learn how to change a non-partitioned table into a partitioned table and partitioned table into a non-partitioned table.
If you are simply adding data to the partitioned table which already has data, then consider these: 1. If all the new data can be assigned to a single new partition, create a new partition and exchange it with the table will be the quickest. Learn the restirctions on exchanging partitions with table. 2. Will the data be simply inserted into the partitioned table? If yes, use direct insert. 3. If there is update involved in addition to insert, consider the "merge" operation.
