Secondly, when you are associating a new result set with a cursor variable that was previously used in an OPEN FOR statement and you did not explicitly close the cursor variable, then the underlying cursor remain open. ResultSet.TYPE_FORWARD_ONLY result sets when used in auto-commit mode are completely cached on the client before the execution of the query is finished.

This read-only attribute should provide the current 0-based index of the cursor in the result set or None if the index cannot be determined. The index can be seen as index of the cursor in a sequence (the result set). The next fetch operation will fetch the row indexed by .rownumber in that sequence.
