Convert SQL query into Drupal 7 PHP rules

SELECT address
  FROM user_address
 WHERE username = '$user->name'
 ORDER BY time DESC
 LIMIT 1

Here is the SQL query that I can understand. How is it possible to convert it into Drupal's 7 PHP? I'm trying to figure that out for a day, and I tried different approaches, but it seems that I am just bad in that.

You can use db_select :

$results = db_select('user_address', 'ua')
        ->fields('ua', array('address'))
        ->condition('ua.username', $user->name, '=')
        ->orderBy('ua.time', 'DESC')
        ->range(0,1)
        ->execute()
        ->fetchAll();
  var_dump($results);

Otherwise you can use db_query if you want to write entire SQL : 

$results = db_query("SELECT address
  FROM user_address
 WHERE username = :username
 ORDER BY time DESC
 LIMIT 1 ", array(':username' => $user->name))->fetchAll();

var_dump($results);

Finally you can use db_query_range :

$page = 0;
$limit = 1
$results = db_query_range("SELECT address
      FROM user_address
     WHERE username = :username
     ORDER BY time DESC", 
    $page * $limit, 
   $limit,   
   array(':username' => $user->name))
   ->fetchAll();

    var_dump($results);

$result = $result = db_select('usr_address','u')
          ->fields('u',array('address','uid'))
          ->range(0,1)
		  ->orderby('time', 'DESC')
          ->condition('u.uid',$uid,'=')
          ->execute();

here is how it actually worked. Thank you for your suggestions, but at the end I made it. By myself. Well, kinda ;D

For that we use db_select() or db_query() - first one preferable. 

 $query = db_select('user_address', 'u');

// Add condition and fields 
$query->condition('u.username', ‘james’)
 $query->fields('u’ array('u.address'));

// execute it

    $result = $query->execute();
   foreach ($result as $record) {
    // Do something with each $record
     }

For more see https://www.drupal.org/docs/7/api/database-api/dynamic-queries/introduction-to-dynamic-queries.

update: see condition portion. Also, you can put this in a module or php executable area of your site or via drush command line. Change the username James to match your need

Try this:

$result = db_select('user_address', 'ua')
		->fields('ua', array('address'))
		->condition('ua.username', $user->name)
		->execute()
		->fetchAll();
