Oracle Error Message
ORA-14293: Number of partitioning columns does not match number of subpartitioning columns
Reason for the Error
When exchanging a partitioned table with a composite partition the number of partitioning columns of the table must match the number of subpartitioning columns of the composite partition.
Solution
Ensure that the number of partitioning columns in the partitioned table is the same as the number of subpartitioning columns in the the composite partition.
