Java GUI with Database

I'm trying to create a simple GUI program that has an access to my derby database.

public void viewRecord(int id)
{

    try{
        GET_RECORD = "SELECT * FROM record where id = ?";

        s = c.prepareStatement(GET_RECORD);
        s.setInt(1, id);
        r = s.executeQuery();
        rs = r.getMetaData();

        System.out.printf("%-15d%-15s%-15d%-15s%-15s",r.getInt(1), r.getString(2), r.getInt(3),r.getString(4),r.getString(5));




    }catch (SQLException ex) {
        java.util.logging.Logger.getLogger(Dbase.class.getName()).log(Level.SEVERE, null, ex);
    }
}

Whenever the function is called, I get

java.sql.SQLException: Invalid operation at current cursor position.

What's wrong with my syntax? Thank you :)

EDIT: Full error message(?)

Solution

You have to use the next call.

ResultSet rs = s.executeQuery();
if (rs.next()) {
    rs.getMetaData()...
}

Quote from the documentation

A ResultSet cursor is initially positioned before the first row; the first call >to the method next makes the first row the current row; the second call makes >the second row the current row, and so on.
