Isnt Failed QA a bit hard too? lol. Had no reason to fail here.

Counter question:
q| INNER JOIN (SELECT DISTINCT subscriptionid FROM subscriptionroutinglist) srl
ON srl.subscriptionid = subscription.subscriptionid|;

Doesnt this looks a bit odd? Joining a subselect. Probably we c/should compare
performance on the various constructs. But I gladly get a response from the
author of doing that all by myself ;)
