Home -> Community -> Usenet -> c.d.o.server -> Re: Query tuning experts: Any hope for tuning query with 5+ joins and a sort?
I think that's probably a fairly precise summary of what often happens -
I remember feeling as if I was the only person in the world who was running OPS with parallel query and partition views in 7.2.3 - and WHY (for example) did the PQ person think that a query would be limited to only 255 bind variables when the PV person changed date predicates to bind variables against every individual table in the view !
