How can I perform exact search strings with with slashes?

Like this:

use strict;
use warnings;

use DBI;
use Test::More tests => 2;

my $dbh = DBI->connect('dbi:SQLite:dbname=/tmp/testdb','','');
$dbh->do ('CREATE TABLE foo (bar VARCHAR(255) NOT NULL)');
my $sth = $dbh->prepare ('INSERT INTO foo values (?)');
$sth->execute ('This has no slashes');
$sth->execute ('/a/b/c');

my $want = '/a/b/c';
$sth = $dbh->prepare ('SELECT * FROM foo WHERE bar = ?');
my $res = $sth->execute ($want);
ok $res, 'True result';
my ($str) = $sth->fetchrow_array;
is $str, $want, 'Strings match';
