Since you're using the JDBC-ODBC bridge, the same code will work to connect to almost any database. You just need to change your ODBC datasource connection.

import java.sql.*; Class.forName(sun.jdbc.odbc.JdbcOdbcDriver"); Connection con=DriverManager.getConnection("jdbc:odbc:DSN);// DSN(Data Source Name) Statement st=con.createStatement(); st.executeUpdate("insert query"); // Retrieve datas ResultSet rs=st.executeQuery("query"); while(rs.next()) { String name=rs.getString(1); int age=rs.getInt(2); } ;P
