Php/mysql - If table is empty echo" "; else

Hey,
This is a simple problem I think. I may have wrong code or something. I need to print something if the table contains no rows. This is what I basically have.

$result = mysql_query( "SELECT * FROM tryouts ORDER BY priority DESC" );

while ($row = mysql_fetch_array($result))
  {
   if($row == 0){
   print "There are no tryouts at the present time.";
   }
  else{
   print"something else"
   }

Can someone tell me where I am going wrong. Thanks in advance.
