One line of perl that assigns a multi-row single-column DBI select to an @array.

I want to select a set of items by ids on some predicate '--PREDICATE--' from an SQL table via DBI.

The long way: 

    use DBI; my $dbh = DBI->connect(...);

    ....

    my @ids = ();

    my $sth = $dbh->prepare('select id from items where '--PREDICATE--
+');

    $sth->execute();
    while (my ($id) = $sth->fetchrow_array()) {
        push @ids, $id;
    }

    $sth->finish();

    ....

I want a shorter one line version.

I am sure there exists some neat contortion using $dbh->select(col|row|all)_(array|hash)(ref)? and referencing/dereferencing - I just can't see it (and am no good with arrays of hash of reference to hash list tap dancing -- $ref->2<-{3,4}[0]{2} -- :P )
