title: Query an object but miss out field/Property (Soda)
body: <p>I'm trying stuff with db4o since a few days but I got a problem.</p>
  
  <p>Imagine this class just for test:</p>
  
  <pre><code>    class Test
  {
    public string TestString
    public int Number;
    public Bitmap Bm;
    public Test2 T2;
  
  }
  </code></pre>
  
  <p>I'm saving the entire class and all sub-objects.
  But when I load it, I don't want Bm to be loaded (just leave it null). How can I leave it out?
  I need to save it because in some cases, I need to load it.
  It's a performance thing because the pictures are really large.</p>
