我有个棘手的问题。我正在用ASP.NET开发一个web应用程序，数据库是SQL Server Express 2005。我编写了一个触发器，在插入或更新记录时更新另一个表的列值

这两张桌子是空的

InvtVendorInvoices（触发器在此表中，触发器名称为Onater_VendorInvoices）

InvtMaster（此表的冒号“invtAmtOthers”值从InvtVendor上的触发器更新）

当我从InvtVendorInvoices表中的SQL Server Management Studio Express插入或更新记录时，InvtMaster表中的“invtAmtOthers”列值正在成功更新。但是，当我从.aspx网页插入或更新记录时，触发器不会触发。有趣的是，尝试从网页插入的记录在InvtVendorInvoices表中被插入或更新，但触发器没有触发，InvtMaster表中的“invtAmtOther”列保持不变

我在互联网上做了很多搜索，但找不到解决方案

请帮我摆脱困境

我们将非常感谢您的帮助

我拥有的数据库表是…

你怎么知道扳机没响？也许触发器确实触发了，但是更新没有找到任何满足条件的记录，其中invtID=@invtID？可能是您从ManagementStudio尝试的测试值在InvtMaster中有相应的记录，但当ASP页面运行代码时，没有记录

我已经解决了这个问题。。。实际上，在父网页中有一个回调面板，它也在更新invtAmtOthers Column。在插入/更新记录后正在执行回调

您好，我已经用InvtMaster中的一条记录测试了我的逻辑，当我在InvtVendorInvoices表中插入一条记录时，我试图通过该记录的invtID。毫无疑问，有一个错误的invtID。此外，如果我们正在更新现有记录，则将在正在更新的表“InvtVendorInvoices”中正确更新该值，但应在InvtMaster表中更新该值的触发器根本不会更新。但是，如果我从SQL Management Studio更新InvtVendorInvoices记录，则其工作正常。我可以看到InvtMaster表中的记录正确更新。为了禁用触发器执行，会话必须非常长。如果在触发器中添加RAISERROR（），则在ASP调用中是否会抛出该错误？如果是，您有证据表明触发器已执行，但更新未完成。嗨，雷姆斯，谢谢您的宝贵建议。我已经在触发器中添加了RAISEERROR（），但是网页逻辑执行时没有抛出任何异常。。。请建议…要禁用触发器，必须明确使用禁用触发器，请参阅。确保您没有犯任何错误，比如更新不同的表（连接字符串指向不同的db）或类似的错误。
