Application does not work when installed with Inno Setup（1个答案）
10个月前就关门了。

如果不存在，则需要创建一个DB，然后保存该表。代码中显示的函数getConnection（）。所实施的程序如下：保存按钮事件调用btnsave（）->insertrecord（）->executequery（）->getConnection（）
我通过以下方式测试了应用程序：
1.在PC 1上安装的eclipse内部-->运行良好。已成功创建数据库并删除表项。
1.创建可运行的Jar并复制到其他笔记本电脑PC 2--。在情况1中运行良好。

1. PC 2上安装了Inno setup。所以，使用INNO来制作安装程序。安装在PC 2上。似乎没有创建数据。如果创建了，不知道会在系统的哪个位置创建？如何通过编程读取数据库路径？

@FXML
    private void btnsave(ActionEvent event) throws Exception{

   System.out.println("New Patient Inserted");

                 + "'"+  selectedGender  + "','"+  newpatient_address.getText() + "',"+  newpatient_mobile.getText() +")";             
       executeQuery(query);
       System.out.println("Saved");
      }
      catch(Exception e) {
       //System.out.println("Execption in Save");
       e.printStackTrace();
