Microsoft SQL Server and Sybase Functions (PDO_DBLIB)

Einführung

Warnung

Diese Erweiterung ist EXPERIMENTELL. Das Verhalten dieser Erweiterung, einschließlich der Funktionsnamen, und alles Andere, was hier dokumentiert ist, kann sich in zukünftigen PHP-Versionen ohne Ankündigung ändern. Seien Sie gewarnt und verwenden Sie diese Erweiterung auf eigenes Risiko.

PDO_DBLIB is a driver that implements the PHP Data Objects (PDO) interface to enable access from PHP to Microsoft SQL Server and Sybase databases through the FreeTDS libary.

This extension is not available anymore on Windows with PHP 5.3 or later.

On Windows, you should use SqlSrv, an alternative driver for MS SQL is available from Microsoft: » http://msdn.microsoft.com/en-us/sqlserver/ff657782.aspx .

If it is not possible to use SqlSrv, you can use the PDO_ODBC driver to connect to Microsoft SQL Server and Sybase databases, as the native Windows DB-LIB is ancient, thread un-safe and no longer supported by Microsoft.

To connect to SQL Server 2005 Express on Windows, do it like this:



$pdo = new PDO ('mssql:host=localhost,1433;dbname=[redacted]', '[redacted]', '[redacted]');



localhost

localhost\SQLEXPRESS

localhost\1433

localhost:1433



will not work on Windows.



localhost,1433



does work.



YMMV on other OS's; try each.



Also make sure your TCP/IP Properties -> IP Addresses are correct under SQL Server Configuration Manager.

If You work with MSSQL Server 7.0/2000/... under Windows and use non latin Encoding then better To use PDO_MSSQL until PDO_ODBC bugs will be fixed (MSSQL ext far more stable and usabe for PHP versions <=5.1.2).

If your MSSQL connection use strings in OEM encoding (cp866 for russian charset) 



1. Run Microsoft Server/Client Network Utility on work PC and UNCHECK "DBLibrary options"/"Automatic ANSI to OEM conversion"



2. Restart Web server if needed.

There is currently little sybase related PDO docs out there. The ones that I found often mention a spec for a dsn that is invalid. Here's how I am currently connecting to sybase ASE:



1. Compile up freetds http://www.freetds.org on top of open client;

2. Add the PDO and PD_DBLIB modules to php 5 as per the documentation; Note: I'm currently using the PDO-beta and PDO_DBLIB-beta;

3. Check mods installed ok using "pear list" and "php -m";



The documentation often says to use "sybase:" as your DSN, this doesn't work. Use "dblib:" instead. Here's an example:



<?php

  try {

    $hostname = "myhost";

    $port = 10060;

    $dbname = "tempdb";

    $username = "dbuser";

    $pw = "password";

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

  } catch (PDOException $e) {

    echo "Failed to get DB handle: " . $e->getMessage() . "\n";

    exit;

  }

  $stmt = $dbh->prepare("select name from master..sysdatabases where name = db_name()");

  $stmt->execute();

  while ($row = $stmt->fetch()) {

    print_r($row);

  }

  unset($dbh); unset($stmt);

?>



Hope this helps.
