  Bug #17173 Partitions: less-than search fails
   
  The problem was that for queries such as field < n, the first call to 
  store_key_image_to_rec would work properly setting the field to null.
  However, on the second call where it should set the non-null value, it would
  not clear the nullness of the field so when val_int() is called on the
  field later, it would return null yet again.

    set field to not null in the case that the field might be null but is not.
