combine two mysql updates into one?

[HDFilmMaker2112]

Would there be any feasible way of combining the two Update statement below into one?

 

The Members Table has id, username, password, and application_id

The Application Table has the application id, the users application information and whether or not the application is approved.

 

if($_GET['approved']=="update"){
$approved=$_GET['approved'];
$approved=sanitize($approved);
if($approved=="y"){
$id=(int)$_GET['id'];
$username=$_GET['username'];
$username=sanitize($username);
$password=$_GET['password'];
$password=sanitize($password);
$approved_sql='UPDATE members SET username="$username" password="$password" application_id="$id"';
$approved_result=mysql_query($approved_sql);
$approved_rows=mysql_affect_rows();
$update_approved_sql='UPDATE application SET approved="y" WHERE id="$id"';
$update_approved_result=mysql_query($update_approved_sql);
$update_approved_rows=mysql_affect_rows();
if($approved_rows==1 && $update_approved_rows==1{
header("Location: ./index.php??admincp=investors&view=applications&id=1&approved=updated");
}
}
}

Just use the alias "AS" for each table name. Same process as joining
