This short code fragment instantiates a DriverManager jdb games item to connect with a database driver and log into your databases, instantiates a Statement item that carries your SQL language question for the databases; instantiates a ResultSet object that retrieves the final results within your question, and executes a simple though loop, which retrieves and displays Those people effects. It is really that simple.
