ORA-14295: column type or size mismatch between partitioning columns and subpartitioning columns

ORA-14295: column type or size mismatch between partitioning columns and subpartitioning columns

Cause: When exchanging a partitioned table with a composite partition the type and size of the partitioning columns of the table must match the type and size of the subpartitioning columns of the composite partition.

Action: Ensure that the type and size of the partitioning columns of the partitioned is the same as the type and size of the subpartitioning columns of the composite partition.
