The question is in the subject. Sorry if it is a newbie question...
When destroying objects, I forgot to clear all pointers to it.
How can I select them?
    

to_delete = []
for row in connection.queryAll("SELECT id FROM my_table"):
   id = row[0]
   try:
      MyTable.get(id)
   except:
      to_delete.append(id)

Oleg.
  
Thanks,
Is there no way of selecting that without doing a python iteration?
In my case, it is object A which has a foreignKey to object B
And I delete some B instances.
