Question

我面临一个奇怪的问题。当我将记录插入主键作为已定义的标识的表中时，将始终插入Id 1的新记录。我很遗憾为什么会这样。如果表中存在重复的主键，则完整性将丢失。

这是表结构

问题是由于交易中的上下文不同而引起的。我在不同的用户活动中将点插入到不同的表中。因此，对于1个活动，多个用户可以获得将插入到多个表中的点，并用于保存已创建多个任务的点。

这是被称为

的方法之一

   public async Task<MethodResult> AddPointsForPollVote(int UserId, int PollOptionId)

       using (var transaction = _entities.Database.BeginTransaction())

               {
                   // Add Daily Activity Point to Post Owner
                   var DailyActivityResultForPollOwner = AddDailyActivityPointsForUser((int)GamificationUserActions.Poll_Vote_Points_To_Poll_Owner, (int)GamificationItemType.Poll,PostOwner);

                   lst.Add(TotalPointsForPollOwner);


                    // Add Topic Points For Post owner

                }


               await Task.WhenAll(lst);


               transaction.Commit();

               return new MethodResult() { Success = true, Message = "Points Added !!" };
           }
           catch (Exception ex)
           {
               transaction.Rollback();
               return new MethodResult() { Success = false, Message = "There was some error !!" };
           }
       }


    }

这是我被调用的方法之一，用于将数据插入表

 public async Task AddDailyActivityPointsForUser(int ActionId, int ItemId, int UserId)
    {

        using (var context = new Entities())
        {

            try
            {
                DailyActivityPoint dailyActivityPoint = new DailyActivityPoint()
                {
                    ActionId = ActionId,
                    CreatedDate = DateTime.Now,
                    ItemId = ItemId,
                    UserId = UserId,
                    PointsAccumulated = await GetPointsAwardedForAction(ActionId)
                };

                context.DailyActivityPoints.Add(dailyActivityPoint);
                await context.SaveChangesAsync();
            }
            catch (Exception ex)
            {
                ErrorLog errorLog = new ErrorLog()
                {
                    CreatedDate = DateTime.Now,
                    ErrorMessage = ex.Message,
                    ModuleName = "GamificationPointsService",
                    CustomMessage = " Error while Adding Daily Activity Points For user : AddDailyActivityPointsForUser ActionId : " + ActionId + " , ItemId : " + ItemId + " , UserId : " + UserId,
                    stackTrace = ex.StackTrace
                };

                context.ErrorLogs.Add(errorLog);
                await context.SaveChangesAsync();
            }

        }


    }

正如你所看到的，当我等待所有这些方法时，在事务内部调用了3个方法并且事务提交。仅为某些表插入重复的主键。休息工作正常。但问题是如何sql允许重复的主键。

请指导我。可能是什么问题。这是我编码的方式[不好的做法或其他什么，这是我第一次使用任务和异步编程[newbee：p]] ??

表脚本：

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [Gamification].[DailyActivityPoints](
    [Id] [int] IDENTITY(1,1) NOT NULL,
    [ActionId] [int] NOT NULL,
    [ItemId] [int] NOT NULL,
    [UserId] [int] NOT NULL,
    [PointsAccumulated] [int] NOT NULL,
    [CreatedDate] [datetime] NOT NULL,
PRIMARY KEY CLUSTERED 
(
    [Id] ASC
)WITH (STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]
GO

ALTER TABLE [Gamification].[DailyActivityPoints] ADD  DEFAULT (getdate())        FOR [CreatedDate]
GO

ALTER TABLE [Gamification].[DailyActivityPoints]  WITH CHECK ADD FOREIGN KEY([ActionId]) REFERENCES [Gamification].[ActionMaster] ([Id])
GO

ALTER TABLE [Gamification].[DailyActivityPoints]  WITH CHECK ADD FOREIGN KEY([ItemId]) REFERENCES [Gamification].[ItemType] ([Id])
GO

ALTER TABLE [Gamification].[DailyActivityPoints]  WITH CHECK ADD FOREIGN KEY([UserId]) REFERENCES [dbo].[Users] ([UserID])
GO

使用EF插入记录时生成的重复主键
