The whole purpose of ORM's /is/ abstraction. The idea is to take the raw concepts of data atoms and abstract them into programmatic entities. This way, you can work with the data directly and not need to worry about SQL semantics and nuance. Additionally, there's the side effect of encouraged utilization of DB server functionality/optimization (views [materialized and direct], triggers, procedures, enforced foreign keys, indices, etc).
