Example #2 PDO_INFORMIX DSN example using a connection string



To work properly, the DSN connection string must not have line breaks.



<?php



$conexion = new PDO("informix:host=host.domain.com; service=9800;

    database=common_db; server=ids_server; protocol=onsoctcp;

    EnableScrollableCursors=1", "testuser", "tespass");



    $sql    = "SELECT * FROM test";

    $prep   = $conexion->prepare($sql);

    $prep->execute();

    $result = $prep->fetchAll(PDO::FETCH_ASSOC);



    var_dump($result);



?>

Bonjour



J'ai appliqué la procédure compilé, installé et charger le php_pdo_inkformix et j'ai utilisé la chaine de connexion suivant :



$bd = new PDO("informix:host=srvinf; service=1526;database=base; server=ol_test; protocol=onsoctcp;EnableScrollableCursors=1", "test", "test");



après éxécution du fichier connexion.php j'ai eu l'erreur :



- Fatal error: Uncaught exception 'PDOException' with message 'could not find driver' in C:\wamp\www\Tests\informix.php on line 5



-PDOException: could not find driver in C:\wamp\www\Tests\informix.php on line 5



Merci de m'assister svp.

When connect to the Dynamic Informix Server, got this error log in apache's error log file:



[Wed Dec 30 12:44:11 2009] [error] [client 1.1.1.1] PHP Fatal error:  Uncaught exception 'PDOException' with message 'SQLSTATE=HY000, SQLDriverConnect: -11005 [Informix][Informix ODBC Driver]Unspecified System Error =  -11005.' in /opt/webroot/informix.php:5\nStack trace:\n#0 /opt/webroot/informix.php(5): PDO->__construct('informix:host=l...', 'username', 'password')\n#1 {main}\n  thrown in /opt/webroot/informix.php on line 5



you should export correct INFORMIXDIR enviroment variable for root user and restart the web server.



and another error:

 

[Wed Dec 30 13:10:10 2009] [error] [client 1.1.1.1] PHP Fatal error:  Uncaught exception 'PDOException' with message 'SQLSTATE=01S00, SQLDriverConnect: -11005 [Informix][Informix ODBC Driver]Invalid connection string attribute.' in /opt/webroot/informix.php:5\nStack trace:\n#0 /opt/webroot/informix.php(5): PDO->__construct('informix:host=l...', 'username', 'password')\n#1 {main}\n  thrown in /opt/webroot/informix.php on line 5



you should let your connection string in one line, without line feed.
