NAME

       DBIx::Class::Helper::ResultSet::OneRow - The first you always wanted

SYNOPSIS

        # note that this is normally a component for a ResultSet
        package MySchema::ResultSet::Person;

        use strict;
        use warnings;

        use parent 'DBIx::Class::ResultSet';

        __PACKAGE__->load_components('Helper::ResultSet::OneRow');

        sub person_named {
           $_[0]->search({ name => $_[1] })->one_row
        }

DESCRIPTION

       This component codifies an alternate version of "first" in DBIx::Class::ResultSet.  In
       practical use, "first" allows a user to do something like the following:

        my $rs = $schema->resultset('Foo')->search({ name => 'bar' });
        my $first = $rs->first;
        my @rest;
        while (my $row = $rs->next) {
           push @rest, $row
        }

       Problematically, if you call "first" without the while loop afterwards and you got back
       more than one row, you are leaving a cursor open.  Depending on your database this could
       increase memory usage or cause errors with later queries.

       Fundamentally the difference is that when you use "one_row" you are guaranteed to exhaust
       the underlying cursor.

       Generally speaking, unless you are doing something unusual, "one_row" is a good default.

METHODS

   one_row
       Limits the ResultSet to a single row, and then returns the matching result object. In case
       no rows match, "undef" is returned as normal.
