Avoiding skipping a row By next() Method of ResultSet

Question

This is a simple code print some rows from a Database. but When I execute this nothing is print on screen. I figured that the problem is rs.next() method is ski

Answer 1

rs.next() will increment cursor in if so if resultset has only one row returned by query then while will move cursor again and no data will get print.Use do..while loop instead.

if (rs.next()) {
            do {
                System.out.print(rs.getString("idUser") + " ,");
                System.out.print(rs.getString("Name") + " ,");
                System.out.print(rs.getString("Email") + " ,");
                System.out.println(rs.getString("country") + " .");
            }while (rs.next());
        }
