Thanks for the update. I just ran counts of the "wrong results" bug fixes in all patchsets from 9.2.0.2 to 10.2.0.4 and 10.2.0.4 is the highest by far with 180! So, I think it's not just our imagination that the software is getting buggier as complexity increases (this was discussed in another thread recently). Maybe Oracle will get to the point some day of offering a stripped down version for all of us that don't need the extra functionality and just want reliability and consistency. Well, I guess we do still have the option of running 8.1.7.4 since it's under Lifetime Sustaining Support :-) -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Henry Poras There are a number of bugs listed in metalink associated with this feature (just search on _optimizer_filter_pred_pullup).
