SQL database not updating?

im trying to make a script where the user can update there details, (in this case the email) but when the script is running it comes up sucess to say its worked and updated. however when i open up my database in notepad or sql workbench the email has not changed its still the same. any ideas what it could be? or maybe im reading my database info wrong?

CODE:

<?php
session_start();
$user_name = "root";
$password = "";
$database = "fixandrun";
$server = "localhost";



$db_handle = mysql_connect($server, $user_name, $password);
$db_found = mysql_select_db($database, $db_handle);


$currentemail = $_POST['currentemail'];
$newemail = $_POST['newemail'];
$confirmnew = $_POST['confirmemail'];
$user = $_SESSION["username"];

if ($db_found)
 {

$dbemail =mysql_query("SELECT email FROM staff WHERE username= '$user'");



//echo "$currentemail";
//echo "$newemail";
//echo "$confirmnew";
//echo "$dbemail";



        if($currentemail == $dbemail || $newemail == $confirmnew)
         {
		   $query = "UPDATE staff SET email = '$confirmnew' WHERE username = '$user'";
		
             
			 
			 if(mysql_query($query)){
              echo "updated";}
              else{
              echo "fail";}
		   
            
          }
         else
        {
         echo" some of your details are incorrect please try again. check that your current email is entered correctly and the new email matches.";
         }
 }
 else
{
print "Database NOT Found.";
mysql_close($db_handle);
}

?>
