很奇怪的SQL更新问题

Question

我有一个名为ApprovalTask​​s表...认证有一个状态栏

我也有一个名为ApprovalsView

当我尝试了直更新视图：

update ApprovalTasks set Status = 2 where ApprovalTaskID = 48 

我收到此错误消息：

Msg 2601, Level 14, State 1, Line 1 
Cannot insert duplicate key row in object 'dbo.ApprovalsView' with unique index 'IX_ApprovalTaskID'. 
The statement has been terminated. 

任何想法为什么会发生这种情况？

下面是创建表的脚本：

Answer 1

看看索引的定义IX_ApprovalTask​​ID 是否有可能存在于ApprovalTask​​ID，StatusID唯一键约束这意味着不存在与状态表= 2 & ApprovalTask​​ID = 48

我同意其他行用户学习，它看起来像有一个有关ApprovalTask​​s UPDATE触发器被插入到ApprovalTask​​ID ApprovalView

尝试运行DISABLE TRIGGER ALL ON ApprovalTasks并重新运行更新

Answer 2

幸运的猜测：任何UPDATE触发器定义？

第二个幸运猜测：ApprovalsView是一个indexed view，它在更新ApprovalTask​​表后违反了其索引。

Answer 3

它看起来像是一个视图已被创建，它是或者包括您正在更新的表，并且当视图正在被更新时更新时发生错误。

也许该视图包含来自不同表格的数据不兼容或者设置了更严格的约束？

Answer 4

由于错误来自对象dbo.ApprovalsView，问题是在ApprovalsTask上尝试更新该表的触发器。我真的认为ApprovalsView是一个表格而不是视图。但是你必须已经检查过了。
