I've been playing with Optiq, and I ran into something that I can't quite figure out how to do: successfully run a query that requires the engine to do multiple passes over a table, something like a self-join or doing a query that has multiple sub-selects over the same table. The queries always compile and execute, they just don't return any results, as if the table had zero rows in it the second time the system tried to read it. My Enumerators support resetting, so I was just curious what I was doing wrong.
