Question

How do I connect to a SQL Server database in CodeIgniter?

I'm currently starting an application in CodeIgniter and I would like to use SQL Server.

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

$db['default']['hostname'] = '#.#.#.27';
$db['default']['username'] = '@@@@@@';
$db['default']['password'] = '@@@@@@@@@';
$db['default']['database'] = '$$$$$$$$$$$$$';
$db['default']['dbdriver'] = 'mssql';
$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;

After auto-loading the database, it shows just a blank white page with no errors. Can you please tell me what other changes I have to make to work with the SQL Server database?

#autoload.php#
$autoload['libraries'] = array('database');

Solution 1

use use $db['default']['dbdriver'] = 'sqlsrv';
and install Microsoft Drivers for PHP for SQL Server on windows

CodeIgniter MSSQL connection

Solution 2

I couldn't get it to work with the supported driver of mssql so I used sqlsrv

I normally connect with ip,port as the hostname, so I changed that.

pconnect was also giving me issues. I set it to FALSE and it started working.

Here is the configuration I got to work:

$db['default']['hostname'] = '127.0.0.1,1433';
$db['default']['username'] = 'username1';
$db['default']['password'] = 'secretpassword';
$db['default']['database'] = 'databasename';
$db['default']['dbdriver'] = 'sqlsrv';
$db['default']['pconnect'] = FALSE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;
