尝试访问 firebird 时出现 pdo 异常

Question

我必须使用 php 和 zend 框架 2 访问 firebird，但出现以下错误：

 /var/www/html/cad/vendor/zendframework/zendframework/library/Zend/Db/Adapter/Driver /Pdo/Statement.php:187

Message:

SQLSTATE[HY000]: General error: -204 Dynamic SQL Error SQL error code = -204 Table  unknown pessoa At line 1, column 19

全局.php

return array(
 'db' => array(
     'driver'         => 'Pdo',
     'dsn'            => 'firebird:dbname=/opt/bancos/teste.fdb',   //array(PDO::ATTR_PERSISTENT => true),
     /*'driver_options' => array(
         PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
     ),*/
 ),
 'service_manager' => array(
     'factories' => array(
         'Zend\Db\Adapter\Adapter'
                 => 'Zend\Db\Adapter\AdapterServiceFactory',
     ),
 ),
 );
?>

local.php

<?php
return array(
    'db' => array(
            'username' => 'sysdba',
            'password' => 'masterkey',
    ),
);
?>

PessoaController.php

 public function indexAction()
 {

        return new ViewModel(array(
                'pessoas' => $this->getPessoaTable()->fetchAll(),
        ));


  }

PessoaTable.php

public function fetchAll()
 {
            try{
    $resultSet = $this->tableGateway->select();
            } catch(Exception $e){
              $e->getMessage();
            }
    return $resultSet;
  }

这里是getPessoaTable()方法

public function getPessoaTable()
 {
    if (!$this->pessoaTable) {
        $sm = $this->getServiceLocator();
        $this->pessoaTable = $sm->get('Pessoa\Model\PessoaTable');
    }
    return $this->pessoaTable;
 }

我已经在 php 中配置了 pdo_firebird.so。它显示在 phpinfo()

Answer 1

错误的重要部分是：“Table unknown pessoa”。您正在从表 pessoa 中选择，根据 Firebird 不存在这样的表。 pessoa 在错误消息中是小写的事实表明您正在使用带引号的标识符。带引号的标识符在 Firebird 中区分大小写。不带引号的标识符是大写的，以使其不区分大小写。

所以这个错误要么意味着表确实不存在，要么 - 当您使用带引号的标识符时 - 表名实际上是 PESSOA。 Firebird 用于带引号/不带引号的标识符的规则将使 SELECT ... FROM pessoa 工作，但 SELECT ... FROM "pessoa" 失败。

我不了解 PDO，因此无法提供 PDO 特定的帮助，但我希望这可以为您缩小范围。
