  Understood. Thank you for the reply. I intended the schema call as
  sort of a diagnostic. The real goal is to insert data into the
  'external' database. So here is the code I have now:
  // code begins
	$dba = array (
              'driver' => 'mysql',
              'database' => 'dolphy_books',
              'host' => 'localhost',
              'username' => 'tim',
              'password' => '******',
			  'port' => '3306',
		);
	Database::addConnectionInfo('db1','default',$dba);
	db_set_active('db1');
	$result = Database::getConnectionInfo('db1');
	drupal_set_message("<b>Now : Connection Info</b>: <pre>" . print_r($result,1) . '</pre>');
	$inserter = db_insert('providers');
  // code ends
  When this code is executed, I get an error: as follows
"""
Additional uncaught exception thrown while handling exception.

Original

PDOException: SQLSTATE[HY000] [2002] No such file or directory in db_insert()

"""
So what am I doing wrong?
Thanks again for the help.
