Joinop [No]Greedy
This statement enables or disables the complex query enumeration heuristic of the query optimizer. The greedy heuristic enables the optimizer to produce a query plan much faster than with its default technique of exhaustive searching for query execution plans when the query references a large number of tables. For details on the greedy optimization heuristic, see the Ingres Database Administrator Guide.
When set joinop greedy is specified, the set joinop timeout statement has no effect.
