Perl DBIx::Class::ResultSet 个不同的值

Question

您好，我想使用 DBix::Class 从数据库中获取唯一的（不同的）值，但无法使用我当前的搜索方法找到如何做到这一点：

my $rs = $schema->resultset('DiscreteCalendar')->search(
        {
            holidaytype => 'W',
            branchcode  => $branchcode,
        },
        {
            select => [{ DAYOFWEEK => 'date' }],
            as     => [qw/ weekday /],
            where       => \['date between ? and ?',$today, $endDate ],

        }
    );

感谢您的热心帮助！

您应该可以将第二个散列中的 distinct => 1 添加到 search 函数，例如：

my $rs = $schema->resultset('DiscreteCalendar')->search(
    {
        holidaytype => 'W',
        branchcode  => $branchcode,
    },
    {
        distinct => 1,
        select => [{ DAYOFWEEK => 'date' }],
        as     => [qw/ weekday /],
        where       => \['date between ? and ?',$today, $endDate ],

    }
);
