php - Zend PDO 错误 - 我该如何调试它？

Question

我在使用 Zend Framework 和 Mysql 时遇到了一个奇怪的问题。我生成了一个查询:

SELECT events.idUser, szForename, szLastname, readers.szName, idZoneFrom, events.dtTime FROM events, users, readers WHERE events.idUser = users.idUser AND events.idReader = readers.idReader AND dtTime >= '2010:02:15 0:00:00' AND dtTime < '2010:02:16 0:00:00' ORDER BY dtTime

如果我在某些控制台(如 pma、navicat 或 shell 客户端)中运行它，查询工作正常，但是当我尝试使用通过 commend 扩展 Zend_Db_Table 的模型运行它时

$arResult = $this->getDefaultAdapter()->query($szQuery)->fetchAll();

出现 1064 错误:

Request Parameters:

array (
  'controller' => 'index',
  'action' => 'events',
  'module' => 'default',
  'idUser' => '0',
  'dt' => '02/15/2010',
)  

如何调试才能发现问题？？或者也许你知道我做错了什么？

附言。我使用同一个数据库用户进行 php 和查询测试...

正如我所见，您的 SQL 语句有保留字。您应该尝试建立自己的连接，以便它可以自动转义标识符，或者您应该自己手动完成。对于第一个选项，试试这个:

  $options = array(Zend_Db::AUTO_QUOTE_IDENTIFIERS => false);
  $params = array(
      'host'           => 'host',
      'username'       => 'user',
      'password'       => 'secret',
      'dbname'         => 'db',
      'options'        => $options
  );
  $db = Zend_Db::factory('Pdo_Mysql', $params);
