Class::DBI::Iterator(3User Contributed Perl DocumentaClass::DBI::Iterator(3pm)

       Class::DBI::Iterator - Iterate over Class::DBI search results

               my $it = My::Class->search(foo => 'bar');

               my $results = $it->count;

               my $first_result = $it->first;
               while ($it->next) { ... }

               my @slice = $it->slice(10,19);
               my $slice = $it->slice(10,19);



       Any Class::DBI search (including a has_many method) which returns
       multiple objects can be made to return an iterator instead simply by
       executing the search in scalar context.

       Then, rather than having to fetch all the results at the same time, you
       can fetch them one at a time, potentially saving a considerable amount
       of processing time and memory.

       Note that there is no provision for the data changing (or even being
       deleted) in the database inbetween performing the search and retrieving
       the next result.
