[MonetDB-users] PF: "Group By" work-around no longer working?

Hi all, I am using MonetDB Nov2008-SP1 release with XQuery. I need to group the results that I retrieve by file. Since XQuery does not have a 'group by' function as in SQL, I was using the workaround of Borkar and Carey, see http://www.idealliance.org/proceedings/xml04/papers/229/XQueryExtensionsFina... This was working fine for the version of half year ago, but with the latest release the trick with 'distinct-values' is no longer working. The results are returned not grouped by file, e.g. {A,A,A}, {B,B}, {C,C,C,C}, etc. Is this true for other users as well? Am I going crazy? ;) Could someone please test whether this still works? Thanks and regards, junte
