I'm trying to for a new PDO connection using the following code.

new PDO("mssql:driver=????;Server={$serverName};Database={$databaseName}", $username, $password, array(PDO::ATTR_PERSISTENT => false, PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION));

I'm not sure what drivers to use? Or how to install them. I can connect perfectly fine using the mssql_connect function in PHP but I want to use the PDO library instead.

My php.ini settings for mssql are:

ssql

MSSQL Support   enabled
Active Persistent Links     0
Active Links    1
Library version     FreeTDS

Directive   Local Value Master Value
mssql.allow_persistent  On  On
mssql.batchsize 0   0
mssql.charset   no value    no value
mssql.compatability_mode    Off Off
mssql.connect_timeout   5   5
mssql.datetimeconvert   On  On
mssql.max_links Unlimited   Unlimited
mssql.max_persistent    Unlimited   Unlimited
mssql.max_procs Unlimited   Unlimited
mssql.min_error_severity    10  10
mssql.min_message_severity  10  10
mssql.secure_connection Off Off
mssql.textlimit Server default  Server default
mssql.textsize  Server default  Server default
mssql.timeout   60  60

The PDO mssql driver is no more, use sqlsrv (under php windows) or dblib (under php linux)

  • using dblib still produces the missing drivers error. "Uncaught exception 'PDOException' with message 'could not find driver'". I find it strange that mssql_connect works fine yet I have to do something in order to get the PDO side working. I'm not very familiar with linux which means that I'm unsure of getting the drivers that I need sorted out? – richie May 12 '11 at 15:05

    You need to enable pdo_dblib.so in your php.ini and set up FreeTDS under Linux. – James May 13 '11 at 17:21
  • how do you enable pdo_dblib in configure? also I am using centos 5 32bit, how would I set it up? – shorif2000 Mar 01 '13 at 14:09
  • pdo_dblib no longer works with PHP 5.4+... I can't find a suitable solution to this problem. – Dominick Mar 24 '14 at 20:48
  • @James Is the PHP [Microsoft PDO_SQLSRV](http://php.net/manual/en/ref.pdo-sqlsrv.php) deprecated or is there no problems using it? – Honinbo Shusaku Aug 24 '15 at 14:18
  • @Abdul Not that I'm aware of, why do you ask? – James Aug 24 '15 at 15:09
  • @James I misunderstood your answer and thought that you can't use PDOs with mssql, but I'm guessing that's the `PDO ("mssql:host=$hostname;dbname=$dbname","$username","$pw");` one that you can't use, and I need to import the MS drivers – Honinbo Shusaku Aug 24 '15 at 15:15
  • Correct, "mssql" stopped being provided with PHP in 5.3 and "sqlsrv" and "dblib" are the current drivers (to my knowledge, it's been a while) – James Aug 24 '15 at 16:56

I am running Ubuntu 14.04. Trying to connect to MSSQL I got "Uncaught exception 'PDOException' with message 'could not find driver'". It seems that I was missing the dblib/sybase PHP extension.

I had to run:

sudo apt-get install php5-sybase freetds-common libsybdb5 \ 
&& sudo apache2ctl restart

Works fine now.

Try 

$dbh = new PDO ("mssql:host=$hostname;dbname=$dbname","$username","$pw");

$hostname may need to be configured as either...
$hostname.':'.$port;

OR 

$hostname.','.$port;

    The error message that I get is Uncaught exception 'PDOException' with message 'could not find driver' – richie May 11 '11 at 09:35

The dblib/sybase PHP extension tip posted by Karl Wilbur worked for me. The pre-installation check page for LimeSurvey now shows

PHP PDO driver library- Microsoft SQL Server (dblib), MySQL

Just make sure you find and install the version that aligns with the PHP version you are using;

Prompt>sudo apt-get install php<appropriate version>-sybase freetds-common libsybdb5 Prompt>sudo apache2ctl restart
