Class::DBI::Iterator(3User Contributed Perl DocumentatiClass::DBI::Iterator(3)

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

SYNOPSIS
	       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);

	       $it->reset;

	       $it->delete_all;

DESCRIPTION
       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.

CAVEAT
       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.
