1. queryMaybe :: (MonadQualify ConfigureQuery m, MonadQuery m) => Relation () r -> m (Record Flat (Maybe r))

   relational-query	Database.Relational.Relation

   Join sub-query. Query result is Maybe. The combinations of query and queryMaybe express inner joins, left outer joins, right outer joins, and full outer joins. Here is an example of a right outer join:

   outerJoin = relation $ do
   e <- queryMaybe employee
   d <- query department
   on $ e ?! E.deptId' .=. just (d ! D.deptId')
   return $ (,) |$| e |*| d
   

2. uniqueQueryMaybe' :: UniqueRelation p c r -> QueryUnique (PlaceHolders p, Record c (Maybe r))

   relational-query	Database.Relational.Relation

   Join unique sub-query with place-holder parameter p. Query result is Maybe.

3. toMaybe :: Table r -> Table (Maybe r)

   relational-query	Database.Relational.Table

   Cast phantom type into Maybe type.

4. hoistMaybe :: forall (m :: Type -> Type) a . Monad m => Maybe a -> MaybeT m a

   relational-query-HDBC	Database.HDBC.Schema.Driver

   Hoist from Maybe context into MaybeT.
