The following is the ORA-14520 error message, you can learn the cause and solution of the Oracle database error.

ORA-14520 Tablespace string block size [string] does not match existing object block size [string]

Cause: A DDL statement was issued that would require a tablespace of a block size different from the block size of the specified partitioned object to be assigned either: (1) As the object’s default tablespace (or one of the object’s partition-level default tablespaces, if composite partitioning is being used) OR (2) To one of the object’s partitions/subpartitions.

Solution: Specify a tablespace of the same block size as the partitioned object.
