I worked through SelectTranslator.appendQueryColumns(..) and I assume this method would require quite a bit of re-hashing -- yes; looks like hard work to change! In actual fact, I want to get the primary keys so that I can randomly page-through a list of ObjectId-s faulting a page at a time. Looking at SelectTranslator.appendIdColumns, this may happen to mostly give me the behaviour I need. I see this is tied to "setPageSize()" where the feature assumes linear pagination through a result-set of indeterminate size. The problem is that I want to know the size of the result-set so I know how many pages to present. Does there exist a mechanism to get the size of the results-set when in "pagination mode" at all or does one have to just page through [prev|next] until you hit the end? Failing that, would it be possible for me to alter "SelectQuery" and "SelectTranslator" to allow an option where only the primary keys for the query-root were returned in "data rows" mode? > I see.
