Question

i have written a code, where if a button is pressed, values from textfields shall be taken to create a record in a database. the code compiles but when i run it, i get this error message:

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'From, To, TotalDays, VacationType, Notes, Signature, Date) VALUES('','','','',''' at line 1

Any suggestions?

    final JButton btnSubmit = new JButton("Submit");
    btnSubmit.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent arg0) {                 
        try {

            String vacationid = text_vacationID.getText();
            String staffid = text_staffID.getText();
            String from = text_from.getText();
            String to = text_to.getText();
            String totaldays = text_totalDays.getText();
            String vacationtype = text_vacationType.getText();
            String notes = textArea.getText();
            String signature = text_signature.getText();
            String date = text_date.getText();


            String sql = "INSERT into vacation (VacationID, StaffID, From, To, TotalDays, VacationType, Notes, Signature, Date) VALUES" + "(?,?,?,?,?,?,?,?,?)";    

            PreparedStatement prest = con.prepareStatement(sql);
            prest.setString(1, vacationid);
            prest.setString(2, staffid);
            prest.setString(3, from);
            prest.setString(4, to);
            prest.setString(5, totaldays);
            prest.setString(6, vacationtype);
            prest.setString(7, notes);
            prest.setString(8, signature);
            prest.setString(9, date);

            prest.executeUpdate();
            JOptionPane.showMessageDialog(frmBookVacation, "Vacation has been booked for Employee with ID: " + vacationid);


        } 

        catch (SQLException e) {
        //System.out.println("Record couldn't be added!");
        e.printStackTrace();
        JOptionPane.showMessageDialog(frmBookVacation, "Vacation couldn't be booked. Please try again.");
        }
        }

        });
    btnSubmit.setBounds(201, 350, 89, 23);
    panel_1.add(btnSubmit);

Answer 1

From is a reserved word in MySQL. Also you can get rid of all those fields from your table in the code as the following:

String sql = "INSERT into vacation VALUES" + "(?,?,?,?,?,?,?,?,?)";    

That should work.
