使用IN子句的Symfony2.3原始SQL查询 [英] Symfony2.3 raw sql query with IN Clause

问题描述

我正在尝试使用针对entry子句的entityentitymanager运行原始sql查询，如下所示.

I was trying to a run raw sql query with doctrine entitymanager for IN clause as shown below.

    $idSArray  = Array ( [0] => 1 [1] => 2 )

    $stmt = $this->getDoctrine()->getEntityManager()
    ->getConnection()
    ->prepare('SELECT t1.id , t1.name , t2.start_date , t2.end_date 
    FROM table1 t1 , table2 t2 
    WHERE t1.id = t2.matchId AND  t1.id IN (:ids)');


    $params = array(
      'ids'  => implode( ",", $idSArray )
    );
    $stmt->execute($params);
    $results = $stmt->fetchAll();

但是我只能得到Id = 1的结果.如果我将WHERE IN条件硬编码为

But I am only getting result for Id = 1. If I hardcode the WHERE IN condition as

     WHERE t1.id = t2.matchId AND  t1.id IN (1,2)');

然后获得两个ID的结果.谁能告诉我在传递$ params数组时我做错了什么.我还打印了输出1,2的爆破结果.因此，我无法找到错误以及使用IN子句执行原始sql查询的方式.

Then getting result for both the Ids. Can anyone tell me that what I am doing wrong in passing the $params array. I have also print the implode result which outputs 1,2. So I am not able to find the mistake and also the way to perform raw sql query with IN clause.

推荐答案

答案:

• DoctrineDBALTypes转换

所以您至少犯了两个错误.首先是@Alarid所说的:您不应该破坏您的数组.第二个是在运行准备好的语句时必须对IN clause使用DoctrineDBALTypes Conversion.

So there are at least two mistakes you did. The first is what @Alarid said: you should not implode your array. The second is that you have to use DoctrineDBALTypes Conversion for IN clause when running a prepared statement.

最后您的查询如下:

$stmt = $this->getDoctrine()->getEntityManager()
        ->getConnection()
        ->prepare('SELECT t1.id , t1.name , t2.start_date , t2.end_date
        FROM table1 t1 , table2 t2
        WHERE t1.id = t2.matchId AND  t1.id IN (:ids)');

$stmt->bindValue('ids', $idSArray, \Doctrine\DBAL\Connection::PARAM_INT_ARRAY);
$stmt->execute();

或替代:

$stmt = $this->getDoctrine()->getEntityManager()
    ->getConnection()
    ->executeQuery('SELECT t1.id , t1.name , t2.start_date , t2.end_date
        FROM table1 t1 , table2 t2
        WHERE t1.id = t2.matchId AND  t1.id IN (:ids)',
        array('ids' => $idSArray),
        array('ids' => \Doctrine\DBAL\Connection::PARAM_INT_ARRAY)
    )
;
