PDO_ODBC DSN — Connecting to ODBC or DB2 databases
Описание
The PDO_ODBC Data Source Name (DSN) is composed of the following elements:
- DSN prefix
-
The DSN prefix is
odbc:. If you are connecting to a database cataloged in the ODBC driver manager or the DB2 catalog, you can append the cataloged name of the database to the DSN. - DSN
-
The name of the database as cataloged in the ODBC driver manager or the DB2 catalog. Alternately, you can provide a complete ODBC connection string to connect to a database as described at » http://www.connectionstrings.com/.
- UID
-
The name of the user for the connection. If you specify the user name in the DSN, PDO ignores the value of the user name argument in the PDO constructor.
- PWD
-
The password of the user for the connection. If you specify the password in the DSN, PDO ignores the value of the password argument in the PDO constructor.

On MS SQL Server there is a convenient way to help troubleshooting database server performance problems is to use the APP attribute, like this:
<?php
$dsn = 'DRIVER=FreeTDS;SERVERNAME=server1;DATABASE=testdb;APP=My PHP Application;UID=user;';
?>
This will show the "My PHP Application" text in ProgramName column of the sp_who2 procedure in MS SQL Server.
Just an exemple of an odbc connection string to MSSQL 2005 :
<?php
$cnx = new PDO("odbc:Driver={SQL Native Client};Server=250.156.0.1;Database=myDataBase; Uid=userName;Pwd=thePassword;");
?>
