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

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


Cause:


User attempted to create a UNIQUE partitioned index whose partitioning columns do not form a subset of its key columns which is illegal



Action:


If the user, indeed, desired 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' partitioning columns form a subset of its key columns
