Question

我在使用数据库的codeigniter中建立连接时遇到问题。我已经尝试了很多并测试了不同人给出的许多解决方案，但到目前为止还没有成功。

我在codeigniter中的配置是：

$db['default']['hostname'] = 'DX-PC\MSSQLSERVER';
//$db['default']['port'] = 1433;
$db['default']['username'] = 'myusername';
$db['default']['password'] = 'mypass';
$db['default']['database'] = 'mydbname';
$db['default']['dbdriver'] = 'sqlsrv';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = FALSE; //default: TRUE
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;

所以，它给了我以下错误：

发生数据库错误无法使用提供的设置连接到数据库服务器。

同样，我使用以下代码尝试与MS SQL服务器建立连接，而不使用codeigniter：

    echo 'called';

    echo "<br>";

    $serverName = "DX-PC\\MSSQLSERVER"; //serverName\instanceName
    $connectionInfo = array( "Database"=>"mydbname", "UID"=>"myusername", "PWD"=>"mypass");
    $conn = sqlsrv_connect( $serverName,$connectionInfo);
    if( $conn ) {
        echo "Connection established.<br />";
    }else{
        echo "Connection could not be established.<br />";
        echo "<pre>";
        print_r(sqlsrv_errors());
        echo "</pre>";
    }

它给了我这些错误：

called Connection could not be established.

我尝试过来自不同论坛和stackoverflow的每个解决方案，但没有成功。请帮助我。感谢

Answer 1

过去我也有问题，所以我用经典的方式做到了：

$server = "x.x.x.x\MSSQL2005,1435";
$user = "xxxx";
$pass = "xxxx";

$this->ms  = mssql_connect($server, $user, $pass) or die ("No connection");

Answer 2

是的，我已经弄明白并且现在正在工作。以下更改使其正常工作。

以前必须完成的配置。 ie（扩展名：sqlsrv _ * .dll等在php.ini中添加等）
将.htaccess中的重写规则从RewriteRule ^（。）$ /index.php?/$1 [L]更改为RewriteRule ^（。）$ /yourrootfolder / index.php ？/ $ 1 [L]（礼貌SHAZ）
其次，因为我有一个名为MSSQLSERVER的默认实例，所以它不需要写$ db [＆＃39;默认＆＃39;] [＆＃39;主机名＆＃39;] =＆＃39; DX-PC \ MSSQLSERVER＆＃39 ;;而是WROTE $ db [＆＃39;默认＆＃39;] [＆＃39;主机名＆＃39;] =＆＃39; DX-PC＆＃39;;

我希望这可以帮助别人。感谢。

MSSQL服务器未在codeigniter中配置。即没有建立连接
