PDO_ODBC-DSN(3) 1 PDO_ODBC-DSN(3)
PDO_ODBC DSN - Connecting to ODBC or DB2 databases
The PDO_ODBC Data Source Name (DSN) is composed of the following elements:
o 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.
o 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/.
o 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.
o 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.
