当我的站点上发生应用程序错误并且它与格式错误的 SQL 查询连接时，我想知道解决问题的查询。但这并不容易，当出现这样的错误时，给出的信息是这样的：

发生错误

应用程序错误

异常信息：

消息：SQLSTATE [42S22]：未找到列：1054 'where 子句'中的未知列 'p.name'

如何记录导致错误的 SQL 查询？

我找到了一个相当复杂但有用的解决方案，将以下代码添加到 ErrorController.php：当异常属于 Zend_Db_Statement_Exception 类时，转到特定的跟踪行，获取在那里使用的 Zend_Db_Select 参数并获取部分SQL 子句（where、from、order、group 等），并将它们记录到日志文件中。恶心，不是吗？;) 但有效 :)

这是要插入的代码ErrorController.php 

    $thread_id = exec('echo $$');

    if (get_class($errors->exception) == 'Zend_Db_Statement_Exception') {
      $trace = $errors->exception->getTrace();

      foreach(array('columns', 'from', 'where', 'order', 'group', 'limitcount', 'limitoffset', 'union') as $queryPartName) {
        $parts = $trace[2]['args'][0]->getPart($queryPartName);
        if ((is_array($parts) && !empty($parts)) ||
            (!is_array($parts) && trim($parts) !== '')) {
          $log->log($thread_id. "\t".strtoupper($queryPartName) .': ', $priority);
          if (is_array($parts)) {
            foreach($parts as $part)
              $log->log($thread_id. "\t"."\t". (is_array($part) ? 'Array: '. implode(', ', $part) : $part), $priority);
          } else
            $log->log($thread_id. "\t"."\t". $parts, $priority);
        }
      }

    }
