Informix prep error

Hi, I'm trying to develop some intranet system based on Informix DB. Standard connection works fine but when I try to exec any SQL I've got a error message.Can someone help me ? I use Ifx IDS 7.3, PHP 4.0.4pl1 on Win2k and IIS 5.0. If I use connection trough ODBC it works fine. Here is sample of my code : $conn = ifx_connect("db@server", "myname", "mypasswd") or die("Couldn't create connection."); echo $conn; $sql = "SELECT * FROM piny ORDER BY klapka"; //line 12 $ifx_prep=ifx_prepare($sql,$conn); and output is : Resource id #1 Warning: Describe fails (E [SQLSTATE=37 000 SQLCODE=-410]) in c:\inetpub\wwwroot\php\bribor.php on line 12 Have you any idea how to solve my problem ?
