Question

我尝试了以下内容：

 $subQuery = $this->createQueryBuilder('teachingEvent')->select('teachingEvent.id')
        ->leftJoin('teachingEvent.timeTableEntry', 'timeTableEntry')
        ->leftJoin('timeTableEntry.course', 'course')
        ->where('course.school = :school' )
        ->andWhere('teachingEvent.date >= :fromDate')
        ->andWhere('teachingEvent.date <= :toDate')
        ->setParameters(array(':fromDate' => $from, ':toDate' => $to, ':school' => $school))
        ->getDQL();


    $query = $this->createQueryBuilder('teachingEvent')
        ->update()
        ->set('teachingEvent.schoolFreeDate', ':schoolFreeDate')
        ->where('teachingEvent.id IN ' . $subQuery)
        ->getQuery();

    return $query->getResult();

当我转出子查询时，我得到了这个：

＆＃34; SELECT teachingEvent.id FROM AppBundle \ Entity \ TeachingEvent teachingEvent LEFT JOIN teachingEvent.timeTableEntry timeTableEntry LEFT JOIN timeTableEntry.course course WHERE course.school =：school AND teachingEvent.date＆gt; =：fromDate AND teachingEvent.date ＆lt; =：toDate

对我来说，似乎应该现在可以正常工作 - 但我收到以下错误消息

[语法错误]第0行，第136栏：错误：预期文字，得到＆＃39; teachingEvent＆＃39;

如果有人能找到错误会很好。

谢谢你！

新年快乐;）！

您也可以首先从第一个查询构建器获取对象，然后执行所需的更新

$sql="SELECT * FROM vinay;";

$result=mysqli_query($conn,$sql);

$resultCheck=mysqli_num_rows($result);

if($resultCheck>o)
{

    while($row=mysqli_fetch_assoc($result))
    {

        echo $row[0];

    }
}

Symfony3 QueryBuilder使用Subquery进行更新
