I need to load data of people and their phones. My entities are Person and PersonPhone.

In PersonPhone we have a list of phones of some person and only one is set as main phone.

I need to load a list of people including just the main phone. I don't want to retrieve all phone list of each person.

I can't do a query of Person and include PersonPhone because I don't know how to filter an include. Is it possible?

DevForce doesn't support filtering on an Include, but there is a workaround using a projection which might help. Here's more information - http://drc.ideablade.com/devforce-2012/bin/view/Documentation/query-include-predicate.

Just as I expected!

Thanks Kim.
