    ResultSet rs = st.executeQuery("SELECT * FROM survey");

    ResultSetMetaData rsMetaData = rs.getMetaData();

    int numberOfColumns = rsMetaData.getColumnCount();
    System.out.println("resultSet MetaData column Count=" + numberOfColumns);

    for (int i = 1; i <= numberOfColumns; i++) {
        System.out.println("column MetaData ");
        System.out.println("column number " + i);

        // get the designated column's SQL type.
        System.out.println(rsMetaData.getColumnType(i));
    }
