This is perfect, thank you :). Couple of additional questions though: 1) When fetching data rows, can I limit the set of fields fetched, i.e. is there an equivalent to EOF’s EOFetchSpecification.setRawRowKeyPaths( NSArray )?
2) When specifying the prefetch, why do I have to addPrefetch( A.SOME_REL.joint() ) instead of just doing addPrefetch( “someRel” )? When traversing further relationships, is this the correct way? : q.addPrefetch( PrefetchTreeNode.withPath( "shop.chain", 1 ) ); Cheers, - hugi // Hugi Thordarson // http://www.loftfar.is/ <http://www.loftfar.is/> // s. 895-6688 > On 31. okt. 2014, at 10:34, Andrus Adamchik <and...@objectstyle.org> wrote: > > If I understand the task correctly, a combination of JOINT prefetching and > "data rows" should probably do the trick: > > SelectQuery<A> query = new SelectQuery<>(A.class); > query.addPrefetch(A.SOME_REL.joint()); > query.setFetchingDataRows(true); > > Andrus > >> On Oct 31, 2014, at 1:14 PM, Hugi Thordarson <h...@karlmenn.is> wrote: >> >> Hi all. >> >> Once again, I’m looking into migrating to Cayenne from EOF :).
