    I have 2 mapped entities: EntityA [ id:long, testMap:Map<EnityB,Integer>, some other properties ] EntityB [ id:long, some other properties ] The mapping of EntityA is like: <class name="EntityA"> <id name="id">...</id> <map name="testMap" table="a_to_b"> <key column="a_id"/> <map-key-many-to-many column="b_id" class="EntityB"/> <element type="integer" column="int_value"/> </map> </class> Now I want to query all EntityA with a certain EnityB as map key: 1. "from a EntityA left join a.testMap b where index(b).id=?"
