It works OK. Thanx everyone.
You may reduce this to one dictionary :)
You want "unique" to contain unique records? The list of keys of a
dictionary is exactly what you want!

unique = {}
for r in result:
   if not unique.has_key(r.data_record_id_):
      unique[r.data_record_id_] = r
return unique.values()

   The "if" test is not neccessary, actually :)
