Java 尝试从数据库Derby DB中选择数据时出现奇怪的错误

我有一个奇怪的错误。我已经用java和derby数据库编写了一个应用程序。因此，我从1年开始使用这个应用程序，但从3天开始，当我尝试执行一个查询以提取数据时，出现了这个错误，但我没有更改代码。 如果我尝试对select数据执行all方法，则会出现以下错误：

你在任何地方都有数据库备份吗？
请不要使用
Vector
ArrayList
很久以来一直是首选。你的Derby数据库在远程文件系统上吗？它所在的机器是否已更改/升级？JDBC驱动程序是否已更新？不，我的程序和数据库在笔式驱动器上。我没有如果我用eclipse打开数据库并尝试使用“从表1中选择*”，我将添加此选项我显示前50条结果。有一个show all record视图，因为在eclipse中有一个默认过滤器，它只显示前50条记录，我可以将其提取并存储在另一个数据库中。如果您能够从表中选择数据，我会立即运行这些选择，并将所有数据复制到一个安全的位置。Derby包含一个很好的系统过程，可以将单个表中的所有数据卸载到一个.csv文件中：如果我使用此函数，我将错误作为我的java应用程序错误。我只能选择前50条记录。我的想法是，我选择前50条记录，然后我尝试删除它，选择另一条50条记录并删除它……我尝试应用我的解决方案上，但如果我尝试删除1条记录，则收到异常。是否有其他解决方案还原此数据库？
