PDO_ODBC DSN

Connecting to ODBC or DB2 databases ()

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.

Examples

Example 1664. 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


Example 1665. 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;


Example 1666. 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:

odbc:Driver={Microsoft Access Driver (*.mdb)};Dbq=C:\\db.mdb;Uid=Admin
