SQL Server（特定）表未更新

Question

我在經典ASP插入/更新中遇到了一個非常奇怪的問題，該問題可以完美運行多年並且從未更改過。 突然，該表不再更新或獲取新記錄。 該代碼不會引發任何錯誤，並且SQL Server日志也不會顯示任何錯誤。 同一數據庫中的其他表工作正常，因此我可以毫無問題地進行插入和更新。

有沒有一種方法可以查明此表正在發生什么或它是否由於某種原因而被鎖定。 我重新啟動了SQL Server和Web應用程序，甚至服務器也沒有運氣。

我直接在SQL Server中更新了表，它可以更新並插入新記錄。

我在另一個表上使用了相同的代碼，並且能夠更新記錄。

有人可以指出正確的方向嗎，因為我不知道可能是什么原因造成的。

提前致謝。

這是代碼：

Answer 1

我注意到UploadQueryString是未定義的，因此如果將其添加為第一行

<%OPTION EXPLICIT%> 

我想您會收到一些有意義的錯誤消息

Answer 2

對於似乎完全不相關的問題，最瘋狂的解決方案是禁用Symantec Endpoint Protection（網絡保護），它的工作原因是我無法解釋！ 謝謝大家的建議。
