ORA-19728: dataobject number conflict between table string and partition string in table string Cause: Thenon-partitioned table has the same data object number as one of the
partitions in the partitioned table. One can not exchange the table with the
partition in this case. Action: Use"alter table move partition" command to move the offending
partition, so that the partition will get a new data object number. Retry the
operation then.
