Hi,
I'm experimenting with starting to use PDO which seems great. However I cannot get the prepare statment to work.
I have shown a snippet of code below which does not return any results when I use the variable substitution feature but when I replace the "?" characters with actual values it works fine.

I cannot see what I'm doing wrong but I'm sure it is something obvious. Can anyone see?

Note that this code comes from wihtin a class hence the use of $this in the example.

Hope this is clear and thanks in advance.
//$sql= 'SELECT * FROM mytable LIMIT 50 OFFSET 0'; # works if I use this
$sql= 'SELECT * FROM mytable LIMIT ? OFFSET ?';
    try {
        $st = $this->db->prepare($sql);#
        $st->execute(array(50, 0));
    } catch (PDOException $e) {
        die($e->getMessage()); 
    }
