# PDO_ODBC DSN

(no version information, might be only in CVS)

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.

## Примеры

Пример 1. PDO_ODBC DSN example (ODBC driver manager)

The following example shows a PDO_ODBC DSN for connecting to an ODBC database cataloged as testdb in the ODBC driver manager:

    odbc:testdb

Пример 2. PDO_ODBC DSN example (IBM DB2 uncataloged connection)

The following example shows a PDO_ODBC DSN for connecting to an IBM DB2 database named `SAMPLE` using the full ODBC DSN syntax:

    odbc:DRIVER={IBM DB2 ODBC DRIVER};HOSTNAME=localhost;PORT=50000;DATABASE=SAMPLE;PROTOCOL=TCPIP;UID=db2inst1;PWD=ibmdb2;

Пример 3. PDO_ODBC DSN example (Microsoft Access uncataloged connection)

The following example shows a PDO_ODBC DSN for connecting to a Microsoft Access database stored at `C:\db.mdb` using the full ODBC DSN syntax:
