Joining on a select causes predicates errror.

(-> (cql/select entities (cql/where (= :entities.entity_id 2)))
 (cql/join
 (cql/select accounts (cql/where (= :accounts.product_id 1)))
 :entity_id))

SELECT entities._,accountssubselect. FROM entities JOIN (SELECT accounts.* FROM accounts WHERE (accounts.product_id = 2)) AS accounts_subselect USING(entity_id) WHERE (entities.entity_id = 1)

Notice how the values specified for :entities.entity_id and :acocunts.product_id are switched
