Dropping Values from a List Subpartition

This operation is essentially the same as described for "About Modifying List Partitions: Dropping Values", however, you use a MODIFY SUBPARTITION clause instead of the MODIFY PARTITION clause. For example, to remove a set of literal values in the value list for subpartition q1_1999_southeast, use the following statement:

ALTER TABLE quarterly_regional_sales
   MODIFY SUBPARTITION q1_1999_southeast
      DROP VALUES ('KS');

For an interval-list composite partitioned table, you can only drop values from subpartitions of range partitions or interval partitions that have been created. To drop values from subpartitions of interval partitions that have not yet been created, you must modify the subpartition template.
