ORA-14293: Number ofpartitioning columns does not match number of
subpartitioning columns
Cause: When exchanging a partitioned table with a compositepartition the
number of partitioning columns of the table must match the number of
subpartitioning columns of the composite partition.
Action: Ensurethat the number of partitioning columns in the partitioned table is
the same as the number of subpartitioning columns in the the compositepartition.
