Processing the Result Set

cursor.fetchone(): Fetches the next row in a query result set and returns a sequence. If no data is available, null is returned.
cursor.fetchall(): Fetches all remaining rows in a query result and returns a list. An empty list is returned when no rows are available.

For GaussDB-specific data types, such as tinyint, the corresponding fields in the query result are character strings.
