Linq ChangeConflictException occurs when submitting DataContext changes
System.Data.Linq.ChangeConflictException: 2 of X updates failed.
at System.Data.Linq.ChangeProcessor.SubmitChanges(ConflictMode failureMode)
at System.Data.Linq.DataContext.SubmitChanges(ConflictMode failureMode)
at PROJECT.Controllers.HomeController.ClickProc(Int32 id, String code, String n)
This is what I get very often. This action is done thousands of times a day, and I get this exception about once every 5 seconds. From what I understand it happens when something changes in the database in the period between creating DataContext
and updating it. Am I right?
How can I fix it?
Update
I just debugged the error and found the following:
Table name: dbo.Stats
current value: 9852039
original value: 9852038
d开发者_StackOverflowatabase value: 9852039
The Stats table is updated constantly. So how can I still make LINQ save the changes. With "classical" SQL Server access through SqlDataCommand
I never had problems like that.
This is due to optimistic concurrency. You can change this behavior but understand what it does before you do it.
