我最近开始使用 ucanaccess 来连接访问数据库（显然），直到现在一切正常。我开始向数据库中插入大约 500,000 行......当我达到大约 400,000 时，程序停止......问题是我看不到异常！我看到了这个-

我看不出异常从哪里开始！它已经发生在我身上一次，但是在进行“压缩和修复”之后，它再次起作用了......现在它没有了。

有谁知道这是怎么回事？

检查以下三件事。

首先，如果您使用任何 IDE，请确保增加日志缓冲区，以便您可以开始此异常。可能不会提供太多帮助，但会比查看介于两者之间的某个地方更好。

其次，数据库文件大小是多少？Access DB 文件大小有限制，有时会导致此类非常规错误。检查出。

第三 - 在使用ucanaccess更新/插入时，请勿打开或尝试对特定数据库执行其他操作。这样做，大多数时候都会导致这个问题。
