You can always fix that by wrapping the value into a quote
And is there any advantage to using quote instead of placeholders? 
sub run_do_with_placeholders($dbh, $id, $name) {
    $dbh->do(qq{
        INSERT INTO customers
        (id,name)
        VALUES(?, ?)},
        undef, $id, $name);
}

There are a few places (table and column names, mostly) where you're required to use quote instead of placeholders, but, IMO, you should always use placeholders for data values where possible and never rely on quoting unless you absolutely have to.
