The C api can do things one row at a time quite easily.
Ruby can be persuaded to do the same thing too.

  "If you want to suppress automatic result set 
  generation by query, set your database handle's 
  query_with_result variable to false:

   dbh.query_with_result = false

I've no idea whether you can convince rails to work with this.
