PDO_ODBC DSN

PDO_ODBC DSN -- Connecting to ODBC or DB2 databases
Description
     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.

     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 |
