EOQualifier or...?

Subject: EOQualifier or...?

I have a situation where I have an entity "Item" that is related to many "Picture" items. I'm trying to fetch all "Items" that have no related "Pictures"...in sql I would write a query like:

SELECT * FROM Item i
LEFT JOIN Picture p ON i.id = p.itemID
WHERE p.id is null

In other words I'd like to select all where Item.pictures.count == 0. What's the easiest / best / most correct way to do this with EO?

Thanks!

John
