class NoCursorDQLFetchStrategy(NoCursorFetchStrategy): (source)

View In Hierarchy

Cursor strategy for a DQL result that has no open cursor. This is a result set that can return rows, i.e. for a SELECT, or for an INSERT, UPDATE, DELETE that includes RETURNING. However it is in the state where the cursor is closed and no rows remain available. The owning result object may or may not be "hard closed", which determines if the fetch methods send empty results or raise for closed result.
