Using PDO DBLIB driver to connect to MySQL server each SELECT query I've
tried this far returns a valid resultset but PDOStatement::rowCount()
always returns 0.

When i use php 5.1.6 all works fine.

Reproduce code:
---------------
<?php

        $db = new PDO("mysql:host=xxx;dbname=xxx", "xxx", "xxx",  array(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY => true));

        $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

        $r = $db->query("SELECT * FROM xxx");
        echo "<pre>";
        echo "rowCount = ".$r->rowCount();
        echo "</pre>";

?>



Expected result:
----------------
rowCount = 540554

Actual result:
--------------
rowCount = 0
