Oracle Error Message
ORA-14283: UNIQUE constraints mismatch in ALTER TABLE EXCHANGE SUBPARTITION
Reason for the Error
One of the tables named in the ALTER TABLE EXCHANGE SUBPARTITION command has a UNIQUE constraint for which no matching (vis-a-vis key columns) constraint is defined on the other table or a matching constraint is defined on the other table, but it differs from that defined on the first table vis-a-vis being enabled and/or validated.
Solution
Ensure that for every UNIQUE constraint defined on one of the tables named in the ALTER TABLE EXCHANGE SUBPARTITION statement there is a matching (vis-a-vis key columns and being enabled and/or validated) UNIQUE constraint defined on the other table. If UNIQUE constrains are enabled, UNIQUE constraints on the partitioned table should be enforced using local indexes.
