在 symfony 中执行自定义 SQL

问题描述

我正在尝试执行一些自定义 SQL 来检索 Symfony 应用程序中的一些模型对象.我在网上找到了一个教程，上面说这样的话可以让我执行查询，尽管不填充模型(填充模型不是主要问题，它只是用于只读数据).

I'm trying to execute some custom SQL to retrieve some model objects in a Symfony application. I found a tutorial on the web that said something like this would allow me to execute the query although not populate the models (populating the model isn't a major issue, it's just for read only data).

$pdo = Doctrine_Manager::getInstance()->connection()->getDbh();
$pdo->prepare("SELECT * from something complicated");
$pdo->execute();
$this->sensorReadings = $pdo->fetchAll();

但我遇到了一个错误:

Fatal error: Call to undefined method PDO::execute()
in sfproject/apps/frontend/modules/site/actions/actions.class.php 

推荐答案

$query = "SELECT * from something complicated";
$rs = Doctrine_Manager::getInstance()->getCurrentConnection()->fetchAssoc($query);

结果集是一个数组.
