我创建了一个java应用程序，它将从表中选择ceratin值并使用hibernate打印它。我使用HSQLDb作为后端。但执行后我收到错误用户缺少权限或找不到对象：但我正在获取查询当我第一次执行时
休眠：从 IF_MAIN ifmain0_ 中选择 ifmain0_.IF_ID 作为 IF1_0_，ifmain0_.IF_NAME 作为 IF2_0_
但在那之后我得到了上述错误。所以我删除了 sample.lck 文件，再次执行两次后我得到了同样的错误

谁能告诉我为什么我会收到这个错误。我尝试使用其他数据库，如 mysql 和 oracle 10g。我能够连接并获得结果，但是当我使用 HSQL Db 时出现此错误
