Hey guys,
after having spent a couple of hours figuring out why a subquery annotated
with `Count` fails, I came to the conclusion that `Count` in a query
causes `GROUP BY` clauses added to it, which in turn renders the SQL
subquery useless.
Please investigate this example which I just added to Stack Overflow as a
resolution, and see what I'm talking about:
