Re: [hibernate-dev] Query#iterate

I'm sorry, I apparently confused iterate() with scroll() then, so forget what I wrote before ^^ In face of that new info, I actually don't know of any actual users. After thinking a bit about it, why not make that behavior configurable via setProperty and drop that method?

ScrollableResults do not meet that need? Unfortunately I don't know what a shallow query is or what the implication on the query or the processing of being shallow are. Just what I said before. "shallow" is simply a boolean flag that is part of the translator. It is set to true when the translation is triggered from Query#iterate. When the translation is triggered from Query#list or Query#scroll it is set to false. I guess this has to do with how row processing is done? The main thing is effects is the SQL we render. For "entity returns" it simply selects the ids and we expect to then load them (immediately!) by that id (N+1). Its usefulness is actually VERY limited in scope as it actually performs horrendously in, what, 95-99% of use cases? Interestingly it really does not have much effect on "row processing".
