Hello, I'm somewhat new to Perl and inexperienced with SQL. I've been using DBIx::Simple to pull information from various tables and it has worked great until I have an array of about 40,000 values that I need to match in @all_ids. I've tried a few other methods but run out of memory or it takes too long to complete. After I pull these values, I then need to get the number of unique parts. What is the most efficient way to query an sql table involving a large array?

my @data = $dbh->select(
    'table', '*', {
    ww    => [@ww],
    id => [@all_ids],
    }
)->hashes;

my $counter = 0;
for (my $i = 0; $i < @data; $i++) {
    my $part = $data[$i]{'part'};
    my $n_value = $data[$i]{'n'};
    if ($part !~ m/^0000000.*/) {
        if (!$seen{$part}) {
            $seen{$part} = 1;
            $counter++;
        }
    } elsif (!$seen{$n_value}) {
        $seen{$n_value} = 1;
        $counter++;
    }
}
print "The uin count is $counter\n";
}
