> {code:sql}
> SELECT COUNT(*) FROM Person p, PhoneNumber pn WHERE p.id=pn.id AND p.id=1
> {code}
> or
> {code:sql}
> SELECT COUNT(*) FROM Person p INNER JOIN PhoneNumber pn ON p.id=pn.id WHERE p.id=1
> {code}
> both return only 1.
> NOTE: issue appears also when using only nested descriptors in the proto schema.
