Very strange SQL update issue - sql

Question

I have a table called ApprovalTasks... Approvals has a status column
I also have a view called ApprovalsView
When I try a straight update :
update ApprovalTasks set Status = 2 where ApprovalTaskID = 48
I'm getting this error message:
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.
Any idea why this is happening?
Here is the create table script:

Answer 1

Lucky guess: any update triggers defined?
2nd lucky guess: ApprovalsView is an indexed view whose index is violated after updating the ApprovalTask table.

Answer 2

look at the definition of the index IX_ApprovalTaskID
Is it possible there is a unique key constraint on ApprovalTaskID, StatusID which would mean there is another row in the table with Status = 2 & ApprovalTaskID = 48
I agree with user Learning, it looks like there's a FOR UPDATE trigger on ApprovalTasks that is inserting an ApprovalTaskID into ApprovalView
Try running DISABLE TRIGGER ALL ON ApprovalTasks and re-run the update

Answer 3

Since the error is coming from the object dbo.ApprovalsView , the problem is with a trigger on ApprovalsTask which is trying to update that table. I really think that ApprovalsView is a table and not a view. But you must have already checked for that.

Answer 4

It looks like a view has been created which is either of, or includes, the table you are updating and that the error occurs when the view is being updated with the changes.
Perhaps the view contains data from different tables which is incompatible, or has stricter constraints set?
