【问题描述】：
请有人可以说那里有什么问题，为什么会出错，当我注册并登录数据库时。我希望这部分足以说明问题所在。
通过在我的 SQlite 数据库中添加所需的按下按钮信息..
@FXML
public void ActionDelete(Event event)
{
System.out.println(User.getText());
Connection connection = dbregistration.getInstance().getConnection();
items=TableView.getItems();
for(Wallpaper item : items)
{
try {
String DBUsername = User.getText();
String DBEstimateName = EstimateName.getText();
String DBName =item.getName();
String DBPrice= item.getPrice().getText();
String DBAmount=item.getAmount().getText();
String DBVien= item.getVien();
System.out.println(DBUsername+" "+DBEstimateName+ " "+DBName+" "+DBPrice+" "+DBAmount+ " "+ DBVien);
Statement statement = connection.createStatement();
int status = statement.executeUpdate("insert into DBBASE2 (MaterialName,Price,Quantity,Username,EstimateName,Vien) values('"+DBName+"','"+DBPrice+"','"+DBAmount+"','"+DBUsername+"','"+DBEstimateName+"','"+DBVien+"')");
if (status>0) {
System.out.println("user registered");
}
}
catch (SQLException e) {
e.printStackTrace();}
}
}
有错误

能否通过直接连接到 SQLite 连接到数据库并调用相同的
INSERT语句？您是否以某种方式将数据库锁定在不同的窗口/进程中？请edit您的问题并添加该信息，并删除最后似乎是杂散字符。
