我正在尝试使用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如何在我的Windows 2008 Server 2008 R2上安装pdo_sqlsrv?
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[IMSSP]: This extension requires the Microsoft SQL Server 2012 Native Client ODBC Driver to communicate with SQL Server. Access the following URL to download the Microsoft SQL Server 2012 Native Client ODBC driver for x86: http://go.microsoft.com/fwlink/?LinkId=163712 '
我从 http://www.microsoft.com/en-us/download/details.aspx?id=20098(SQLSRV30.EXE) 我下载了驱动器已将这些驱动程序放置在Server 2008 R2服务器上安装php的ext目录中。
我也有在php.ini文件的扩展名列表的末尾添加这两条线
extension=php_pdo_sqlsrv_53_nts.dll
extension=php_sqlsrv_53_nts.dll
我使用PH PVersion 5.3.19 服务器API CGI/FastCGI的 线程安全禁用
我确实看到了pdo_sqlsrv
,但我没有看到客户端API版本。
我还需要做些什么才能够使用PDO连接到具有SQL数据库的远程服务器?我需要在远程服务器上安装任何东西吗?
这是我的PHP我管理部分
的截图这是我的连接类
<?php
class connection {
private $connString;
private $userName;
private $passCode;
private $server;
private $pdo;

);
function __construct($dbName = DATABASE_NAME, $serverName = DATABASE_HOST){
//sets credentials
$this->setConnectionCredentials($dbName, $serverName);
//start the connect
$this->startConnection();
}
function startConnection(){
$this->pdo = new PDO($this->connString, $this->userName, $this->passCode, $this->pdo_opt);
if(! $this->pdo){
$this->errorMessage = 'Failed to connect to database. Please try to refresh this page in 1 minute. ';
$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)
{
$start = microtime(true);
$cmd = $this->pdo->prepare($query);

//return last insert id

return $cmd->fetchColumn();
}
public function getError(){
if($this->errorMessage != '')
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;
}
}
?>
这是我用我的同班同学拉的数据集
<?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();
?>
我甚至试过这段代码,所以我不会用我的类和我仍然得到相同的错误
$ss = new PDO("sqlsrv:server=SQLSERVER; Database=databaseName", "userName", "Password");
没有。它应该很好去..尝试使用'sqlsrv_query'。 – Kermit 2013-04-25 20:10:03
您的评论。什么是sqlsrv_query?我该如何使用它? – Mike 2013-04-25 20:12:35
** sqlsrv_query **是可替代PDO的** sqlsrv _ **系列PHP函数的一部分。这将*不会*帮助你,因为你的问题在PHP之外,在驱动程序/操作系统级别。 – 2015-06-16 01:16:55
