ORA-14188

Error: ORA-14188: sub-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 subpartitioning columns do not form a subset of its key columns which is illegal.

Acción: If you want to create an index whose subpartitioning 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 subpartitioning columns to ensure that the index's subpartitioning columns form a subset of its key columns.
