I am trying to create a table that has a couple of unique fields like so

Where containableGraphics is another table with the fields ID and ParentID. I am trying to say that Position(s) are UNIQUE with respect to each Parent. But I don't think this type of constraint will work. I can always do this;


But I didnt want to redundantly enter the ContainerID when this info is also referred to by the containableGraphics ID since a containableGraphics can have only 1 parent which is a containerGraphics.
Any ideas on this??
