    There are two options:

    1. EJBQL. This supports "compound" results, with each result object
    being an Object[], with each array element corresponding to a separate
    entity or a scalar.
    2. DataRows (mentioned already in this thread). Then each row is a map
    that can contain arbitrary data.
