This is something I have in my development code:

--- class.t3lib_db.php~ 2006-08-24 12:01:17.000000000 +0200
+++ class.t3lib_db.php  2006-08-24 12:01:29.000000000 +0200

         */
        function sql_fetch_assoc($res)  {
+               if (!$res) {
+                       echo
"<pre>".$sql."\n".mysql_error()."\n".print_r(debug_backtrace(),
true)."</pre>";
+                       die();
+               }
                return mysql_fetch_assoc($res);
        }

It proved to be VERY useful.

Cheers,
