# accessing $wpdb from a different WordPress database

 * I’m creating a plugin and I need to access an external WordPress database’s `
   $wpdb` to find that database’s prefix. The connection to the external database
   is defined in `$conn` and the connection works. However, I’m not sure what code
   to write in order to get the external database’s prefix. I was hoping something
   like this would work:
    `$db_prefix_conn = $conn->base_prefix;` But that doesn’t
   do anything. Any help is greatly appreciated.
