sample script:

<?php
     $db_id=sybase_connect("DSCOMPONENTS_DEV", "", "");
     if(!$db_id) {
       print ("Connect to database fails<BR>");
     } else {
       print ("Connection established<BR>");
       $rc=sybase_select_db("master");
       $db_result=sybase_query("select * from sysusers order by name");
       $selected_rows=sybase_num_rows($db_result);
       print ("Selected Rows= $selected_rows<BR>");
       /*Funny stuff !! Activate the next line and fix the problem*/
       /*$rc=sybase_data_seek($db_result,0);*/
       while ($db_row = sybase_fetch_row($db_result)) {
         print (implode($db_row, " : "));
         print ("<BR>");
       }
    }
?>

description:
The sample script loses usually the second result line. If the error does not turn up in the first time, make a reload for the same page an then you got it. It is not relevant how to order the result, everytime the second line is empty.
The line with the sybase_data_seek-statement fixes the problem.
