When wherequery has any of its subquery against ObjectTable (which will

be for all the queries against ObjectTable), the first query that should
be processed is the one against the ObjectTable. The dimension of the
result returned by DbQueryUnit for ObjectTable and MessageTable are
different. Therefor before doing the AND operation make sure the
ObjectTable results are the first subquery to be processed.
