It includes performing operations between sets, numeric functions like average or sum, etc.. In JPOX it will implemented as exemplified here http://www.jpox.org/servlet/jira/browse/CORE-2861 Sadly, JDOQL 2 is not capable to compete with JPQL in this aspect. Regardless the above issue, are there plans to expand the JDOQL or even JDO 2 in general based on new user requests/requirements? Regards, Erik Bengtson
