如何将Codeigniter与MSSQL（SQL Server）连接？

Question

My server use Windows Server with MSSQL 2012. While I am use OS X (El Capitan) with XAMPP (Apache) for Mac and develop website using Codeigniter 2.2.0.

Here is my configuration :

$active_group = 'my_mssql';
$active_record = TRUE;

$db['my_mssql']['hostname'] = 'xx.xx.xx.x';
$db['my_mssql']['username'] = 'wow_queue';
$db['my_mssql']['password'] = 'wow12345';
$db['my_mssql']['database'] = 'queue_sys';
$db['my_mssql']['dbdriver'] = 'mssql';
$db['my_mssql']['dbprefix'] = '';
$db['my_mssql']['pconnect'] = TRUE;
$db['my_mssql']['db_debug'] = TRUE;
$db['my_mssql']['cache_on'] = FALSE;
$db['my_mssql']['cachedir'] = '';
$db['my_mssql']['char_set'] = 'utf8';
$db['my_mssql']['dbcollat'] = 'utf8_general_ci';
$db['my_mssql']['swap_pre'] = '';
$db['my_mssql']['autoinit'] = TRUE;
$db['my_mssql']['stricton'] = FALSE;

but the results is :

Are my settings be wrong?

I just want to be able to connect to that server. Does anyone have any advice on solving this?

Answer 1

You may want to try odbc driver (built-in db driver in PHP). Mssql driver doesn't come convenient in PHP.

I got this working with CI 2.2.0 connected to MSSQL 2014 database (all Windows platform). I've also tried this using MSSQL 2012 before.

$active_group = 'my_mssql';
$active_record = TRUE;

$db['my_mssql']['hostname'] = 'Driver={SQL Server Native Client 11.0};Server=Host\Instance;Database=queue_sys;';
$db['my_mssql']['username'] = 'wow_queue';
$db['my_mssql']['password'] = 'wow12345';
$db['my_mssql']['database'] = '';
$db['my_mssql']['dbdriver'] = 'odbc';
$db['my_mssql']['dbprefix'] = '';
$db['my_mssql']['pconnect'] = FALSE;
$db['my_mssql']['db_debug'] = TRUE;
$db['my_mssql']['cache_on'] = FALSE;
$db['my_mssql']['cachedir'] = '';
$db['my_mssql']['char_set'] = 'utf8';
$db['my_mssql']['dbcollat'] = 'utf8_general_ci';
$db['my_mssql']['swap_pre'] = '';
$db['my_mssql']['autoinit'] = TRUE;
$db['my_mssql']['stricton'] = FALSE;

Note:

SQL Server Native Client 11.0 or SQL Server Native Client 10.0 , just play with both settings.

Server=xx.xx.xx.x usually is in the format Server=Host\\Instance

Detail steps for How to connect SQL Server with PHP in WampServer

step 1)

download the appropriate driver based on your php version, check using php_info() function, for me 5.6, so the appropriate driver is SQLSRV30, found in the following link https://www.microsoft.com/en-us/download/details.aspx?id=20098

step 2) extract the drives in C:\\wamp\\bin\\php\\php5.6.19\\ext focus on the following .dll file they should be there, otherwise we can't connect with SQL, these are

php_sqlsrv_56_nts.dll and php_sqlsrv_56_ts.dll

step 3) enable the drives in php.ini as follow, which is found in C:\\wamp\\bin\\apache\\apache2.4.18\\bin as follow

extension=php_sqlsrv_56_ts.dll extension=php_sqlsrv_56_nts.dll

step 4) go to DB_driver.php line 96 found in C:\\wamp\\www\\public\\system\\database\\DB_driver.php please replace the mysqli by sqlsrv

public $dbdriver = ' mysqli  '; 
 public $dbdriver = 'sqlsrv'; 

step 5) last and most important part, go to CI database config in database.php file which's found in C:\\wamp\\www\\public\\application\\config\\database.php adjust the params accordingly...

$db['default'] = array(

'dsn' => '',
'hostname' => 'ip address for sql server,port', // it should be SQL TCP enabled and firewall permitted for SQL port, whether default or custom.
'username' => 'your user name here',
'password' => 'your pwd here',
'database' => 'your db here',
'dbdriver' => 'sqlsrv',
'dbprefix' => '',
'pconnect' => TRUE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'autoinit' => TRUE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE

);

happy coding...

The error is showing that SQLSRV driver implies the DLL is not loading ever. check your php_info() The SQLSRV driver requires for it. check this for step by step solution
