Jak kilka SELECT połączyć w 1 zapytanie sql Opcje

[zielq701]

Witam wszystkich,
piszę proste api do planera dnia. Czy da się zastąpić 3 SELECTY jednym aby otrzymać następującą odpowiedź:

[PHP] pobierz, plaintext 
Array
(
    [2015-05-22] => Array
        (
            [timed] => Array
                (
                    [0] => Array
                        (
                            [id] => 16

                            [task] => Testowe zadanie specjalne
                            [note] => Testowo testować testowane zadania. Test testowy testowany testowo wielokrotnie.
                            [priority_id] => 1

[PHP] pobierz, plaintext 

Bardzo mi zależy na takiej strukturze tabeli. Tak wygląda teraz część mojego kodu w php:

[PHP] pobierz, plaintext 
class DataProvider {
private $db;
 
    public function __construct($db)
    {
        $this->db = $db;
    }
 
    public function getRequestData()
    {
        return json_decode(file_get_contents('php://input'), true);
    }
 
    public function getTasks($userId, $date)
    {
        //pobiera zadania ktore maja okreslona godzine i NIE zostaly wykonane
        $sql = "SELECT ds_tasks.*
                       FROM ds_tasks LEFT JOIN ds_priorities
                       ON ds_tasks.priority_id=ds_priorities.id
                       WHERE user_id = :uid AND `date` = :date AND done = 0 AND`time` IS NOT NULL";
 
        $timed = $this->db->fetchAll($sql, array( 'uid' => (int) $userId, 'date' => $date));
 
       //pobiera zadania ktore NIE maja okreslonej godziny i NIE zostaly wykonane
        $sql = "SELECT ds_tasks.*
                       FROM ds_tasks LEFT JOIN ds_priorities
                       ON ds_tasks.priority_id=ds_priorities.id
                       WHERE user_id = :uid AND `date` = :date AND done = 0 AND `time` IS NULL";
 
        $other = $this->db->fetchAll($sql, array( 'uid' => (int) $userId, 'date' => $date));
 
        //pobiera zadania ktore sa wykonane
        $sql = "SELECT ds_tasks.*
                       FROM ds_tasks LEFT JOIN ds_priorities
                       ON ds_tasks.priority_id=ds_priorities.id
                       WHERE user_id = :uid AND `date` = :date AND done = 1 AND `time` IS NULL";
 
        $done = $this->db->fetchAll($sql, array( 'uid' => (int) $userId, 'date' => $date));
 
        //tworzy tabele z zadaniami
        $tasks = array (
          'timed' => $timed,
          'other' => $other,
          'done' => $done
        );
        return $tasks;
    }
 
    public function getTimeIntervalTasks($userId, $date, $endDate)
    {
        $tasks = array();
 
        while (strtotime($date) <= strtotime($endDate)) {
 
          $tasks[$date] = $this->getTasks($userId, $date);
 
          $date = date("Y-m-d", strtotime("+1 day", strtotime($date)));
        }
 
        return $tasks;
    }
}
