【中文标题】PHP sqlsrv_connect 错误

【英文标题】：PHP sqlsrv_connect Error

【发布时间】：2018-05-02 21:54:26

【问题描述】：

我正在尝试使用 php 连接到 MS SQL Server，但失败了。我正在运行 PHP7.2，并且我已经安装了 Microsoft Drivers 5.2 for PHP for SQL Server 和 Microsoft ODBC Driver 17 for SQL Server。

这是我正在使用的代码...

$serverName = "severname\MSSQLSERVER";

$conn_array = array (
    "UID" => "username",
    "PWD" => "password",
    "Database" => "databasename",
);
$conn = sqlsrv_connect($serverName, $conn_array);
if ($conn)
    echo "connected";
else
    die(print_r(sqlsrv_errors(), true));

这是我收到的错误消息...

更新： 删除实例名称后出现此错误... SQLSTATE[28000]: [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]用户 'USERNAME 登录失败'。

【问题讨论】：

您的实例名称/又名架构名为MSSQLSERVER？不清楚您可能混淆了什么或可能完全错误。

感谢您提供帮助。删除实例名称后，我收到此错误... SQLSTATE[28000]: [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]用户 'USERNAME' 登录失败。

请更新您遇到的新错误问题。

【参考方案1】：

正如@ficuscr 所暗示的，您的问题很可能是实例名称。 MSSQLSERVER 是 default 实例的实例名称，您不使用 server\instance 格式引用它。您只需使用server。您只需对命名实例使用server\instance 格式。

假设是这种情况，您的第一行应该是

$serverName = "severname";

【讨论】：

当我删除实例名称并仅使用服务器名称时，我收到以下错误...

Array ([0] => Array ([0] => 28000 [SQLSTATE] => 28000 [1] => 18456 [code] => 18456 [2] => [Microsoft][ ODBC Driver 17 for SQL Server][SQL Server]用户 USERNAME' 登录失败。[消息] => [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]用户 'USERNAME' 登录失败。）[1] => Array ( [0] => 28000 [SQLSTATE] => 28000 [1] => 18456 [code] => 18456 [2] => [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]登录失败对于用户'USERNAME'。[消息] => [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]用户'USERNAME'登录失败。））

这真的很好！如果您收到该错误，那么您至少已经成功地与 SQL Server 建立了网络连接，该连接比您之前的距离更远。现在您只需要修复您传递的用户名和密码。

“密码”？太棒了！我的行李箱上也有同样的组合！

@ficuscr 经典。可能只是在 dvd 播放器中弹出它。
