Question about result query

[VanPEP]

How can I make iy so that if you query the db, it returns all the info in a formated table (know that part btw) but if there is nothing it returns a message like There are no results instead of just showing an empty table?

Use mysql_num_rows

$sql = mysql_query("Blah blah blah");
$rows = mysql_num_rows($sql);
if($rows == 0) {
    // error out
}
else {
   // display your table
}
