我试图用PDO连接到SQL Server数据库。 我一直在用它挣扎了一点点现在我得到我的网页上这个严重的错误,我试图连接到SQL Server
致命错误:未捕获的异常“PDOException”有消息“SQLSTATE [IMSSP]:这个扩展需要的Microsoft SQL Server 2012本机客户端ODBC驱动程序与SQL Server进行通信。 访问以下网址下载的Microsoft SQL Server 2012本机客户端ODBC驱动程序在x86: http://go.microsoft.com/fwlink/?LinkId=163712 “
我从下载的驱动http://www.microsoft.com/en-us/download/details.aspx?id=20098 (SQLSRV30.EXE)我已经放置在PHP安装在服务器上的ext目录这些驱动程序2008 R2服务器。
我也有在扩展名列表中的在php.ini文件末尾添加这两条线
extension=php_pdo_sqlsrv_53_nts.dll
extension=php_sqlsrv_53_nts.dll
我使用的PH PVersion 5.3.19服务器API CGI / FastCGI的线程安全禁用
我确实看到pdo_sqlsrv
,但我没有看到一个客户端API版本。
这样做还有什么我需要做的是能够使用PDO连接到了SQL databses远程服务器? 我需要在远程服务器上安装任何东西?
这是我的PHP我管理部分截图
这是我的连接类
<?php
class connection {
private $connString;
private $userName;
private $passCode;

$this->errorMessage .= 'However, if you continue to see this message please contact your system administrator.';
echo $this->getError();
}
}
//this will close the PDO connection
public function endConnection(){
$this->pdo = null;
}
//return a dataset with the results
public function getDataSet($query, $data = NULL)

return $this->errorMessage;
else
return true; //no errors found
}
//this where you need to set new server credentials with a new case statment
function setConnectionCredentials($dbName, $serv){
switch($serv){
//MS SQL server
case 'SQLSERVER':
$this->connString = 'sqlsrv:server='.$serv.';database='.$dbName;
$this->userName = 'username';
$this->passCode = 'password';
break;
//the defaults are predefined in the APP_configuration file - DO NOT CHANGE THE DEFAULT
default:
$this->connString = 'mysql:host='.DATABASE_HOST.';dbname='.DATABASE_NAME.';charset=utf8';
$this->userName = DATABASE_USERNAME;
$this->passCode = DATABASE_PASSWORD;
break;
}
}
public function lastQueryTime() {
if(!$this->lastQueryTime) {
throw new Exception('no query has been executed yet');
}
return $this->lastQueryTime;
}
public function lastQuery() {
if(!$this->lastQuery) {
throw new Exception('no query has been executed yet');
}
return $this->lastQuery;
}
}
?>
这是我用我的类来拉数据集
<?php
include('connection.php');
$sql_db = new connection('databaseName','SQLSERVER');
$call_details = $sql_db->getDataSet('SELECT
LocalUserId AS loginName,
RemoteNumberCallId AS PhoneNumber,
SUM(CallDurationSeconds + HoldDurationSeconds + LineDurationSeconds) AS totalTalk
FROM dbo.CallDetail WHERE LocalUserId = \'blah\' AND RemoteNumberCallId = \'123456789\'
GROUP BY LocalUserId, RemoteNumberCallId');
$call_details->endConnection();
?>
我甚至试过这个代码,所以我不会用我的课,我仍然得到同样的错误
$ss = new PDO("sqlsrv:server=SQLSERVER; Database=databaseName", "userName", "Password");
