 * @todo Support seeing the "results" of the called procedure or
 *       function. This needs further reseach because a procedure
 *       does not necessarily contain a SELECT statement that
 *       produces something to see. But it seems we could at least
 *       get the number of rows affected. We would have to
 *       use the CLIENT_MULTI_RESULTS flag to get the result set
 *       and also the call status. All this does not fit well with
 *       our current sql.php.
 *       Of course the interface would need a way to pass calling parameters.
 *       Also, support DEFINER (like we do in export).
