Description:
------------
With IBM DB2 9.1 you can use XQuery for XML data.

This code produces an error, but works in the DB2 Control Center:

xquery db2-fn:xmlcolumn('TALKS.TALKS');

Sorry for the German error messages...

Reproduce code:
---------------
<?php
    $stmt = $db->prepare("xquery db2-fn:xmlcolumn('TALKS.TALKS')");
    if ($stmt->execute()) {
        foreach ($stmt->fetch() as $data) {
            var_dump($data);
        }
    } else {
        print_r($stmt->errorInfo());
    }

Expected result:
----------------
After XML serialization:
