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.

       Example #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

       Example #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;

       Example #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:

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