Answer 1

hmm, allow me to explain my logic to all of you again. This is my first time using last_insert_id and have no idea how to implement. But i have found out it is performed an insert query into a table that contains an AUTO_INCREMENT field. And my placemarkid is a primary key which is auto_increment.
Here is my code
public boolean add(Placemark pm){
        boolean result = false;
        try {
            PreparedStatement pstmt = con.prepareStatement("insert into placemark(placemarkid, userid, date, time,longtitude,latitude) values(?,?,?,?,?,?)");
            pstmt.setInt(1, pm.getPlacemarkid());
            pstmt.setInt(2, pm.getUserid());
            pstmt.setDate(3, pm.getDate());
            pstmt.setTime(4, pm.getTime());
            pstmt.setDouble(5, pm.getLongtitude());
            pstmt.setDouble(6, pm.getLatitude());
            int num = pstmt.executeUpdate();
            if(num==1)
                result = true;
            //  PreparedStatement pstmt1 = con.prepareStatement("SELECT LAST_INSERT_ID FROM placemark WHERE placemarkid = ?");
            //pstmt1.setInt(1, pm.getPlacemarkid());
            // ResultSet rs = pstmt1.executeQuery();
            pstmt.close();
            // pstmt1.close();
        } catch(SQLException e){
            e.printStackTrace();
            result = false;
        return result;
    }ok, i need to query out the last insert id and set it into the placemark object using the "setPlacemarkId" method.Also, the sql statement to get the last inserted id is "SELECT LAST_INSERT_ID()".Can anyone please help me of the last_insert_id. I;m quite confused to the previous post that u all have send me as this is my first time using.
