Connect sqlsrv in Xampp

问题

I have installed Xampp with a CodeIgniter installation. I want to connect from CodeIgniter to a SQL database.

I changed the database config file and set the dbdriver to sqlsrv.

$active_group = 'default';
$active_record = TRUE;

$db['default']['hostname'] = 'IP Adress;
$db['default']['username'] = 'DBUserName';
$db['default']['password'] = 'DBPassword';
$db['default']['database'] = 'DBName';
$db['default']['dbdriver'] = 'sqlsrv';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = 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;

In my controller I have the following code to try the connection:

$this->load->database();

$db_obj = $this->db->load('sql_Test',TRUE);
$connected = $db_obj->initialize();

if (!$connected){
    $db_obj = $this->d->load('yyy',TRUE);
} 
else{
    die('connected');
}

I have the following error:

Fatal error: Call to undefined function sqlsrv_connect() in C:\xampp\htdocs\system\database\drivers\sqlsrv\sqlsrv_driver.php on line 76

I have read on a forum that I have to change line 89 from sqlsrv_driver.php:

function db_pconnect()
{
    // $this->db_connect(TRUE); original
    return $this->db_connect(TRUE);
}

What do I wrong?

EDIT- First you need to download the driver http://msdn.microsoft.com/en-us/sqlserver/ff657782.aspx

Now go to your XAMPP installation and search for php.dll It will display correct PHP dll you have.

1) move following files to xampp/php/ext directory.

php_sqlsrv_53_nts_vc9.dll
php_pdo_sqlsrv_53_nts_vc9.dll

2) If you have php5ts.dll then move following files to xampp/php/ext directory.

php_sqlsrv_53_ts_vc9.dll
php_pdo_sqlsrv_53_ts_vc9.dll

above files should be used if your PHP version is compiled with Visual C++ 9.0 . Else following files should be used.

1) If you have php.dll then move following files to xampp/php/ext directory.

php_sqlsrv_53_nts_vc6.dll
php_pdo_sqlsrv_53_nts_vc6.dll

2) If you have php5ts.dll then move following files to xampp/php/ext directory.

php_sqlsrv_53_ts_vc6.dll
php_pdo_sqlsrv_53_ts_vc6.dll

Now we have to load files that we added recently. Open the php ini file and add entry in the area of dynamic extensions as follow.

extension=php_sqlsrv_53_nts_vc9.dll
extension= php_pdo_sqlsrv_53_nts_vc9 .dll

Save the ini files and restart XAMPP

$check= @$CI->load->database($config, TRUE); // ommit the error
if ($check->call_function('error') !== 0) {
    // Failed to connect
}

I don't know for sure what you are trying to do but in codeigniter you don't need to initialise database, CI automatically does it for you

so-

$this->load->database();

$db_obj = $this->db->load('SQL_Test',TRUE);
$connected = $db_obj->initialize();

this is not needed.

You just need to load the model and in model start performing queries. $this->load->database(); In controller you need to load the model like-

$this->load->model('my_model');

then call the model function in which you have written the queries.

$this->my_model->myfunction();

Your XAMPP setup doesn't have sqlsrv support. You need to enable it in php.ini.

extension=php_sqlsrv.dll
extension=php_pdo_sqlsrv.dll
