# PDO_ODBC DSN

(PECL PDO_ODBC >= 0.1.0)

PDO_ODBC DSN — Connecting to ODBC or DB2 databases

### Beschreibung

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.
