maybe you could try odbc_num_rows($yourResultID)
this will return 0 if there is nothing in the result set or the number of
rows otherwise
look in the php manual for more info
http://www.php.net/manual/en/function.odbc-num-rows.php
note that it might return -1 (thus not work as intended) with some drivers,
look in the user contributed notes at the bottom of the manual page, there
seems to be a few solution to that -1 problem
