When you update a note in database you already have something using what you can identify it. In your example you already have $id which should be containing the value of data you have recently updated. If you don't have id and you try to update with name or something different after update you can simply retrieve updated data with simple query:

select * from table_name where your condition

Note: mysql_* functions are deprecated and won't be supported in future versions. You should be using either mysqli_* or PDO.
