The RowLoadID value in each row of a load isolated table records the LoadID value. The LoadID used in a newly inserted row is derived from the last committed LoadID value for the table as recorded in DBC.TVM.CurrentLoadId. For more information, see Teradata Vantage™ SQL Request and Transaction Processing, B035-1142.
