当我尝试在 yii 框架中执行查询时连接被重置

Question

当我尝试连接到我的数据库时，一切正常，但是当我尝试使用 query() 命令执行 SQL 语句时，我得到此错误：

The connection was reset

The connection to the server was reset while the page was

页面未加载。

$sql = <<<SQL
SELECT
1
FROM
dual
SQL;
$oci=Yii::app()->db;
$command = $oci->createCommand($sql);
$dataReader = $command->query();

我正在尝试在 index.php 页面中执行此操作，如果我评论最后一行，页面加载成功。

我测试了与 echo isset(Yii::app()->db); 的连接，我得到了 1。

我正在使用 oci8Pdo.OciDbConnection class。

编辑：

print_r($command) 结果：

CDbCommand Object ( [params] => Array ( ) [_connection:private] => OciDbConnection Object 
( [pdoClass] => Oci8PDO [connectionString] => oci:dbname=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=********)(PORT=1521))

编辑 2：

'db1'=>array(
      'class'=>'ext.oci8Pdo.OciDbConnection',
      'connectionString' => 'oci:dbname=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=**********)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=*******)));',
      'username' => '***',
      'password' => '****',
'emulatePrepare' => true,
      /*
       * enableProfiling and enableParamLogging are working like normal; Default is false.
       */
      'enableProfiling' => true,
      'enableParamLogging' => true,
),

Answer 1

您正在使用 Yii::app()->db 但您的配置文件似乎正在使用 "db1" .你能检查一下吗？这个问题似乎与 Yii 无关，而只是无法连接到正确的数据库系统。

Answer 2

好吧，显然 oci8Pdo.OciDbConnection 在 PHP 5.1 中不起作用，所以我使用了具有正确字符集的 CDbConnection，它运行良好。
