ORA-14039

Error: ORA-14039: partitioning columns must form a subset of key columns of a UNIQUE index

Causa: An attempt was made to create a UNIQUE partitioned index whose partitioning columns do not form a subset of its key columns which is illegal.

Acción: If you want to create an index whose partitioning columns do not form a subset of its key columns, it must be created as non-UNIQUE; otherwise, correct the list of key and/or partitioning columns to ensure that the index's partitioning columns form a subset of its key columns.
