Re^3: Tie'ing a dbh result set?

If you can guarantee that the array will only be accessed:

in order
read only
only once per element
you know how many elements there are

then you can do it by simply writing a FETCH which returns the next resultset and a FETCHSIZE which returns the correct size. It would work correctly for usage like:

foreach my $result_ref (@array) {
  process($result_ref);
}

Otherwise, please explain how you make it function as an iterator.
