	// size as the number of columns.
	// The dest should not be written to outside of ScanRow. Care
	// should be taken when closing a RowScanner not to modify
	// a buffer held in dest.
	ScanRow(dest []driver.Value, rowIndex int64) dbsqlerr.DBError

	// NRows returns the number of rows in the current result page
