                {

                    destinationConnection.Open();

                    using (SqlBulkCopy bulkCopy =

                               new SqlBulkCopy(destinationConnection))

                        bulkCopy.DestinationTableName = "dbo.destination_table";

                        try

                        {

                            bulkCopy.WriteToServer(reader);

                        }
