nextRow
public T nextRow()
Description copied from interface:ResultIteratorReturns the next result row that is, depending on the query, may be a scalar value, a DataRow, or an Object[] array containing a mix of scalars and DataRows.- Specified by:

-
skipRow
public void skipRow()
Description copied from interface:ResultIteratorGoes past current row. If the row is not needed, this may save some time on data conversion.- Specified by:
