Thanks for the reply Kathrine. So in theory however if Derby’s estimate works correctly, the sorting should spill to disk and there should be no OOM errors, right?
I was looking for the thread about this but can't find it just now and apologize for being so vague. Perhaps though this will jog someone else's memory.
As I recall, the scenario that was causing trouble was one where to start out with there was enough memory for the sort and then during processing other things consumed memory meaning there no longer was room. Having chosen to go down this path there was no turning back and Derby would run out of memory on the query. As to whether it "should" spill to disk in that case I don't know, I think the determination was at least that no one knew how to do do it. Again, I am having trouble finding the thread, so perhaps I dreamed all this....
