Save button doesn't work in management program

Frank Seo :

public void saveEmployeeButtonPushed(ActionEvent event) {
    if (validPasswords()) {
        try {
            if (employee != null) {
                updateEmployee();
                employee.updateEmployeeInDB();
            } else {
                if (imageChanged) {
                    employee = new Employee(firstNameTextField.getText(),
                            lastNameTextField.getText(), eType.getValue().toString(),
                            phoneNumberTextField.getText(), Integer.parseInt(salaryTextField.getText().toString()),
                            birthday.getValue(), imageFile, pwField.getText());

                } else {
                    if (Validation.emptyCheck(firstNameTextField.getText()) == false) {
                        JOptionPane.showMessageDialog(null, "Please enter the first name");
                    } else {
                        employee = new Employee(
                                firstNameTextField.getText(), lastNameTextField.getText(),
                                eType.getValue().toString(), phoneNumberTextField.getText(),
                                Integer.parseInt(salaryTextField.getText().toString()), birthday.getValue(),
                                pwField.getText());
                    }
                }
                errMsgLabel.setText("");
                employee.insertIntoDB();
            }
            SceneChanger sc = new SceneChanger();
            sc.changeScene(event, "Employee.fxml", "Employee");

        } catch (Exception e) {
            errMsgLabel.setText(e.getMessage());
        }
    }
}

This is the method for save

public void updateEmployeeInDB() throws SQLException {

    Connection conn = null;
    PreparedStatement preparedStatement = null;

    try {
        conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/bakery", "root", "a3756421");
        String sql = "UPDATE employee SET eName1=?,eName2=?,eType=?,phoneNumber=?,eSalary=?,birthday=?,imageFile=?" + "WHERE eId = ?";
        preparedStatement = conn.prepareStatement(sql);
        Date db = Date.valueOf(birthday);
        preparedStatement.setInt(1, eId);
        preparedStatement.setString(2, eName1); 
        preparedStatement.setString(3, eName2);
        preparedStatement.setString(4, eType);
        preparedStatement.setString(5, phoneNumber);
        preparedStatement.setInt(6, eSalary);
        preparedStatement.setDate(7, db);
        preparedStatement.setString(8, imageFile.getName());

        preparedStatement.executeUpdate();
        preparedStatement.close();

    } catch (Exception e) {
        System.err.println(e.getMessage());
    } finally {
        if (conn != null)
            conn.close();
        if (preparedStatement != null)
            preparedStatement.close();

    }

}

This is the method for update employee

CREATE TABLE employee
(
    eId INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
   eName1 VARCHAR(30),
    eName2 VARCHAR(30),
    eType VARCHAR(30),
    phoneNumber VARCHAR(12),
     eSalary INT,
     birthday DATE,
     imageFile VARCHAR(100)
);

This is the table I'm using in the database

Even when I press the save button, not only it doesn't update into the database but also it doesn't change the scene. I have checked whether the save button has a problem with the scene-builder but it was all fine.

bakero98 :

Your preparedStatement has wrong order. You are setting id first but in query It is last. I also changed sql query as there is no need for +

String sql = "UPDATE employee SET eName1=?,eName2=?,eType=?,phoneNumber=?,eSalary=?,birthday=?,imageFile=? WHERE eId = ?";
    preparedStatement = conn.prepareStatement(sql);
    Date db = Date.valueOf(birthday);

    preparedStatement.setString(1, eName1); 
    preparedStatement.setString(2, eName2);
    preparedStatement.setString(3, eType);
    preparedStatement.setString(4, phoneNumber);
    preparedStatement.setInt(5, eSalary);
    preparedStatement.setDate(6, db);
    preparedStatement.setString(7, imageFile.getName());
    preparedStatement.setInt(8, eId); // THIS IS LAST NOW
