public class Main {

public static void main(String[] args)

{

try {

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

}

catch(Exception e)

{

System.out.println(e);

}

try

{

Connection conn;

Statement stmt;

ResultSet rs;

conn=DriverManager.getConnection("Jdbc:Odbc:anamika","anamika","anamika");

stmt=conn.createStatement();

rs=stmt.executeQuery("Select * from table1");

while(rs.next())

{

System.out.println(rs.getString("name"));

System.out.println(rs.getString("rollno"));

}

}

catch(Exception e)

{


}

}

}

Output
