Question

我遇到了一个非常奇怪的问题，经典的asp插入/更新多年来完美无缺，并且从未改变过。出乎意料的是，该表不再更新或获取新记录。代码不会抛出任何错误，SQL Server日志也不显示任何错误。同一数据库中的其他表工作正常，因此我可以毫无问题地插入和更新。

有没有办法找出这张桌子发生了什么，或者是否由于某种原因被锁定了。我重新启动了SQL Server和Web应用程序，甚至服务器都没有运气。

我直接在SQL Server中更新了表，它更新并插入新记录。

我在另一个表上使用了相同的代码，并且能够更新记录。

有人可以指出我正确的方向，因为我对可能导致这种情况的想法有所了解。

提前致谢。

以下是代码：

Answer 1

我注意到UploadQueryString是未定义的，所以如果你把它添加为第一行

<%OPTION EXPLICIT%>

我猜您会收到一些有意义的错误消息

Answer 2

这个完全无关的问题的最疯狂的解决方案是禁用Symantec Endpoint Protection（网络保护），它的工作原因是我无法解释的！谢谢大家的上述建议。
