what would you like the ORM query to return ? Object instances ?
currently, using group_by() and such with Query implies you're getting
individual column tuples back using _values(), in which case its
I.e., *all* columns from th are being added to the columns clause of
the select. According to the SQL standard, these names all need to
be added to the GROUP BY as well - if MS-SQL is allowing only a
partial GROUP BY list, thats just poor behavior on the part of MS-SQL
