It is not possible, your query filter should contain only 'direct" attributes of the class. if you want to run query based on "class number" you need to have to duplicate this property from Classroom to Student.
But I don't understand your problem. If you have 'one" to 'many' relationship and want to run query on children based on parent attributes than every time you will get all children connected with that parent. So why not run query on parent class and collect all the children. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
