{
public static void main (String[] args)
{
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection cn = DriverManager.getConnection("jdbc:odbc:SagarDB");
Statement st = cn.createStatement();
ResultSet rs = st.executeQuery("select * from DemoTable;");

while(rs.next())
{
System.out.println(rs.getString(1)+" " + rs.getString(2)+" " + rs.getString(3)+" ");
