Question

我有一个名为ApprovalTasks的表... Approvals有一个状态列

我还有一个名为ApprovalsView的视图

当我尝试直接更新时：

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.

知道为什么会这样吗？

这是创建表脚本：

Answer 1

幸运的猜测：是否定义了任何更新触发器？

第二个幸运的猜测：ApprovalsView是indexed view，在更新ApprovalTask表后违反了索引。

Answer 2

查看索引IX_ApprovalTaskID的定义是否有可能在ApprovalTaskID，StatusID上有一个唯一的键约束，这意味着表中有另一行，Status = 2＆amp; ApprovalTaskID = 48

我同意用户学习，看起来ApprovalTasks上有一个FOR UPDATE触发器，它将ApprovalTaskID插入ApprovalView

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

Answer 3

由于错误来自对象dbo.ApprovalsView，问题是ApprovalsTask上的触发器正在尝试更新该表。我认为ApprovalsView是一个表而不是视图。但是你必须已经检查过了。

Answer 4

看起来已经创建了一个视图，该视图是您正在更新的表中的一个或包含您正在更新的表，并且在使用更改更新视图时发生错误。

也许视图包含来自不同表的数据，这些数据不兼容，或者设置了更严格的约束？

非常奇怪的SQL更新问题
