The result of ifx_num_rows($result) is always 0!

<?

@$connid=ifx_connect"assdb@ol_assstat", "informix",
"xxx") or die("Error");

$result = ifx_query("SELECT * FROM ae ORDER BY idae", $connid) or die("Error");

$a = ifx_num_rows($result);
echo $a;     // <--- $a is always 0

ifx_free_result($result);

?>

From the PHP manual on "ifx_num_rows()":
---------------------------------------
ifx_num_rows
(3.0.3 - 3.0.16 only, PHP4 )

ifx_num_rows -- Count the rows already *fetched* a query
Description

int ifx_num_rows (int result_id)


Gives the number of rows *fetched* so far for a query with result_id after a ifx_query() or ifx_do() query. 
----------------------------------------

Note "already fetched" and "fetched so far".

Your example hasn't fetched anything, so ifx_num_rows()
has to return 0.
