Symfony2 QueryBuilder SQL到DQL

Question

有人可以幫助我將SQL轉換為有效的Doctrine DQL代碼嗎？

SELECT * FROM tasks WHERE (SELECT COUNT(*) FROM tasks_done WHERE tasks_done.user_id = $userid AND tasks_done.task_id = tasks.id) = 1 AND tasks.user = $userid

我試過的

 $em = $this->getDoctrine()->getManager();

    $qb = $em->createQuery("
        SELECT
            t
        FROM
            tasks t
        WHERE
            t.id IN (
                SELECT
                    td
                FROM
                    TaskDone td
                WHERE
                    td.task_id = t.id
                AND
                    td.user_id = $id
            )

        AND
           t.user = $id
    ");
    $taskDone = $qb->getResult();

這引發以下異常：

[語義錯誤]第0行，第71列靠近“任務t”：錯誤：未定義類“任務”。

我的實體稱為：Task.php和TaskDone.php，類名與文件名相同。 表名稱是：task和task_done

編輯2

我控制器的當前代碼，結果是一個空數組：

$em = $this->getDoctrine()->getManager();

    $qb = $em->createQuery("
        SELECT
            t
        FROM
            SeotoolMainBundle:Task t
        WHERE
            t.id IN (
                SELECT
                    td
                FROM
                    SeotoolMainBundle:TaskDone td
                WHERE
                    td.task_id = t.id
                AND
                    td.user_id = $id
            )

        AND
           t.User = $id
    ");
    $taskDone = $qb->getResult();
    $done = print_r($taskDone, true);

表TaskDone具有條目（ID 1 |任務ID 36 |用戶ID 13）存在ID為36的任務。

Answer 1

我認為您的查詢應該更簡單。

你到底想要什么？ 所有由特定用戶完成的任務？

因此，如果您將這兩個表連接起來並在taskDone.user上進行過濾，則它應該可以工作。

讓我們嘗試一下。

SELECT 
    t
FROM
    SeotoolMainBundle:Tasks t, SeotoolMainBundle:TaskDone td
WHERE
    t.id=td.task_id
AND
    td.user = $userid

（不確定我給您表指定的名稱，我不確定）

也許，我不明白你想要什么。 如果是這樣，請更准確;）
