                  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.
