Question

有人可以帮助我将我的SQL转换为有效的Doctrine DQL代码吗？

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

我尝试了什么：

 $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();

这引发以下异常：

[语义错误]第0行，第71行附近的任务t ＆＃39;：错误：课程＆＃39;任务＆＃39;没有定义。

My Entites被称为：Task.php和TaskDone.php，Classname与filename相同。表名是：tasks和task_done

修改

结构TaskDone.php Entite

<?php

命名空间Seotool \ MainBundle \ Entity;

使用Doctrine \ Common \ Collections \ ArrayCollection; 使用Doctrine \ ORM \ Mapping作为ORM;

{


/**

public function getId()
{
    return $this->id;
}

我的控制器的当前代码，结果是一个空数组：

$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有条目（ID 1 |任务ID 36 |用户ID 13）存在ID为36的任务。

我认为您的查询应该更简单。

你到底想要什么？特定用户完成的所有任务？

所以，如果你加入这两个表并在taskDone.user上过滤，它应该可以工作。

我们试试这个。

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

（小心我给你的桌子的名字，我不确定）

也许，我不明白你想要什么。如果是这样，请更准确;）
