Another approach is to pass only one 'super' parameter which is string with commas in it separating the real parameters. The mysql procedure can then parse the 'super' parameter into the separate real parameters. Example:

declare param2 varchar(100);
begin
 if LOCATE(',',param1) > 0 then
  .. param2= ..
