public static void runTest() throws SQLException, IOException
Connection conn=DriverManager.getConnection("jdbc:derby://localhost:1527/fmgdb;user=fmguser;password=fmguser");
try
Statement stat = conn.createStatement();
stat.executeUpdate("CREATE TABLE Greetings (Message CHAR(20))");
stat.executeUpdate("INSERT INTO Greetings VALUES ('Hello, World!')");
ResultSet result = stat.executeQuery("SELECT * FROM Greetings");
if (result.next())
System.out.println(result.getString(1));
result.close();
stat.executeUpdate("DROP TABLE Greetings");
