如何在带引号的占位符中使用查询？ (perl / postgresql)

#!/usr/bin/perl -w

use Strict;
use DBI;

my $db = "Pg";
my $db_database = "whatever";
my $user = "whatever";
my $password = "whatever";

my $dbh = DBI->connect("dbi:$db:dbname=$db_database",$user,$password);

my $query = $dbh->prepare (q{SELECT
                   arrival_date - INTERVAL '? minutE'
                   FROM emails LIMIT 1})
  or die ("unable to prepare");
$query->execute(60) or die("unable to execute");

print $query->fetchrow_array,"\n";

(arrival_date具有以下格式：带时区的时间戳NOT NULL默认CURRENT_TIMESTAMP)

问题是没有检测到问号占位符,因为它的内部单引号：

DBD::Pg::st execute failed: called with 1 bind variables when 0 are needed

如果我使用qq {},$1占位符,并使用$dbh-> quote尝试了一些变体,它无济于事.我怎样才能做到这一点？
