我正在尝试将数据从datepicker添加到我的数据库中，但是在提交查询之后，在数据库中，没有添加Date列中的日期，我很确定我获得的方式我的代码中的datepicker日期非常错误，但我似乎无法找到解决方法..

@FXML

@FXML

    String Interogare1= "INSERT INTO programaritest(Nume,Prenume,Data,Ora,Departament,Doctor,Nr_telefon) VALUES(?,?,?,?,?,?,?)";

    String nume=Nume.getText();

         Connection conexiune=ConectaredB.logareDB();
        PreparedStatement MG = conexiune.prepareStatement(Interogare1);


        MG.setString(1, nume);
        MG.setString(2, prenume);
        MG.setString(3, data); *Date

        MG.executeUpdate();

         ((Node)event.getSource()).getScene().getWindow().hide();
            Stage PS= new Stage();
            FXMLLoader incarcator= new FXMLLoader();
            Pane parinte = incarcator.load(getClass().getResource("/LicentaApp/Departamente.fxml").openStream());
            Scene scena = new Scene(parinte);
            scena.getStylesheets().add(getClass().getResource("Style1212.css").toExternalForm());
            PS.setScene(scena);
            PS.show();
            System.out.println("Programare adaugata muchacho");



    } catch (SQLException exceptie1) {
        exceptie1.printStackTrace(); // 
    }

}
}

没有错误信息，没有任何错误，只是不起作用。

您使用getValue()获取用户从DatePicker中选择的值。由于这是一个日期，请将其表示为数据库中的日期，并在setDate(...)上使用PreparedStatement。所以：

@FXML 
private void AddProgramare(ActionEvent event) throws SQLException, IOException  {


    String Interogare1= "INSERT INTO programaritest(Nume,Prenume,Data,Ora,Departament,Doctor,Nr_telefon) VALUES(?,?,?,?,?,?,?)";

    String nume=Nume.getText();
    String prenume=Prenume.getText();

    LocalDate data=Data.getValue(); 

    String ora=Ora.getText();
    String departament=Departament.getText();
    String doctor=Doctor.getText();
    String nr_telefon=Nr_telefon.getText();


    try {
        ConectaredB ConectaredB=new ConectaredB();
        Connection conexiune=ConectaredB.logareDB();
        PreparedStatement MG = conexiune.prepareStatement(Interogare1);


        MG.setString(1, nume);
        MG.setString(2, prenume);
        MG.setDate(3, Date.valueOf(data)); 
        MG.setString(4, ora);
        MG.setString(5, departament);
        MG.setString(6, doctor);
        MG.setString(7, nr_telefon);


        MG.executeUpdate();

        // ...
   } catch (SQLException exceptie1) {
       exceptie1.printStackTrace(); /
   }


}

此处需要的导入为java.time.LocalDate和java.sql.Date。

将DatePicker中的数据添加到DB Javafx中
