Use the CREATE TABLE statement to define a primary index and one or more secondary indexes. (You can also define secondary indexes using the CREATE INDEX statement.) You can define the primary index (and any secondary index) as unique, depending on whether duplicate values are to be allowed in the indexed column set. A partitioned primary index cannot be defined as unique if one or more partitioning columns are not included in the primary index.

To create hash or join indexes, use the CREATE HASH INDEX and CREATE JOIN INDEX statements, respectively.
