Exchanging a Subpartition of a *-Hash Partitioned Table

Use the ALTER TABLE EXCHANGE SUBPARTITION statement to convert a hash subpartition of a *-hash partitioned table into a nonpartitioned table, or the reverse. The following example converts the subpartition q3_1999_s1 of table sales into the nonpartitioned table q3_1999. Local index partitions are exchanged with corresponding indexes on q3_1999.

ALTER TABLE sales EXCHANGE SUBPARTITION q3_1999_s1
      WITH TABLE q3_1999 INCLUDING INDEXES;
