DB4O苏打比较字段值

class SomeClass
{
  private DateTime fieldA;
  private DateTime fieldB;
}

使用Soda,选择FieldA大于FieldB的所有对象的正确方法是什么?

像这样?

var query = this.ObjectContainer.Query();
query.Constrain(typeof(SomeClass));
query.Descend("fieldA").Constrain(query.Descend("fieldB")).Greater();
var list = query.Execute();
