Connect to SQL Server through PDO using SQL Server Driver

Question

I am trying to connect to an existing SQL Server database using PDO with the drivers provided by Microsoft.

I have seen examples using odbc, dblib, mssql, etc., however I believe the connection string with these drivers should use 'sqlsrv'?

Are there any good examples of how to properly do this? If I should be doing this via some other method please let me know. Thanks!

Solution 1

Well that's the best part about PDOs is that it's pretty easy to access any database. Provided you have installed those drivers, you should be able to just do:

$db = new PDO("sqlsrv:Server=YouAddress;Database=YourDatabase", "Username", "Password");

Solution 2

Mind you that in my experience and also of other (PHP - Why is new SQLSRV driver slower than the old mssql driver?) that using PDO_SQLSRV is way slower than through PDO_ODBC.

If you want to use the faster PDO_ODBC you can use:

//use any of these or check exact MSSQL ODBC drivername in "ODBC Data Source Administrator"
$mssqldriver = '{SQL Server}'; 
$mssqldriver = '{SQL Server Native Client 11.0}';
$mssqldriver = '{ODBC Driver 11 for SQL Server}';

$hostname='127.0.0.1';
$dbname='test';
$username='user';
$password='pw';
$dbDB = new PDO("odbc:Driver=$mssqldriver;Server=$hostname;Database=$dbname", $username, $password);

Solution 3

Figured this out. Pretty simple:

 new PDO("sqlsrv:server=[sqlservername];Database=[sqlserverdbname]",  "[username]", "[password]");

Solution 4

This works for me, and in this case was a remote connection: Note: The port was IMPORTANT for me

$dsn = "sqlsrv:Server=server.dyndns.biz,1433;Database=DBNAME";
$conn = new PDO($dsn, "root", "P4sw0rd");
$conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );

$sql = "SELECT * FROM Table";

foreach ($conn->query($sql) as $row) {
    print_r($row);
} 

Solution 5

$servername = "";
$username = "";
$password = "";
$database = "";
$port = "1433";
try {
    $conn = new PDO("sqlsrv:server=$servername,$port;Database=$database;ConnectionPooling=0", $username, $password,
        array(
            PDO::ATTR_PERSISTENT => true,
            PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
        )
    );
} catch (PDOException $e) {
    echo ("Error connecting to SQL Server: " . $e->getMessage());
}
