Hi again, >> That doesn't sound like a tremendously good idea to me. > Could you elaborate on the downsides of this approach a bit?
Any other thoughts about the pro/cons replacing IN(subquery) with =ANY(ARRAY(subquery))? Are there patological cases, except when the subquery returns a huge amount of rows? Should Ifile a bug-report about the optimizer trying too hard to collapse the subquery and therefor generating a bad plan?
