DBIx::SearchBuilder::UUsereContributed Perl DocuDBIx::SearchBuilder::Unique(3)

NAME
       DBIx::SearchBuilder::Unique - Ensure uniqueness of records in a
       collection

SYNOPSIS
	   package Foo::Collection;
	   use base 'DBIx::SearchBuilder';

	   use DBIx::SearchBuilder::Unique; # mixin

	   my $collection = Foo::Collection->New();
	   $collection->SetupComplicatedJoins;
	   $collection->OrderByMagic;

	   while (my $thing = $collection->Next) {
	       # $thing	is going to be distinct
	   }

DESCRIPTION
       Currently, DBIx::SearchBuilder makes exceptions for databases which
       cannot handle both "SELECT DISTINCT" and	ordering in the	same
       statement; it drops the "DISTINCT" requirement. This, of	course,	means
       that you	can get	the same row twice, which you might not	want. If
       that's the case,	use this module	as a mix-in, and it will provide you
       with an "AddRecord" method which	ensures	that a record will not appear
       twice in	the same search.
