Sql 解释XDL死锁文件

我生成了以下XML+XDL：

不为人知
不为人知
（@0 nvarchar（512），@1 int，@2 int，@3 bigint，@4 int，@5 int，@6 int，@7 datetime2（7），@8 int，@9 int，@10位，@11位，@12 nvarchar（max））插入[dbo]。[AppEvent]（[MediaPath]，[StorageProvider]，[MediaType]，[MediaSizeInBytes]，[OldSessionState]，[NewSessionState]，[AppEventType]，[EventDate]，[DeviceSessionId]，[TargetSessionId]，[UserId]，[ShouldBeleted]，[HasBeenDeleted]，[Payload]，[LocalBrowserSessionGuid]）
值（@0、@1、@2、@3、@4、@5、@6、@7、@8、NULL、@9、@10、@11、NULL、@12）
选择[上诉]
来自[dbo].[AppEvent]
其中@@ROWCOUNT 0和[AppVentid]=范围\标识（）

我现在正试图理解是什么导致了僵局；我以前从未解释过这种日志。我看到

用户

和

设备会话

之间存在一些争用，但我不确定这是从哪里来的。如何解释XDL/死锁转储？

同样的INSERT语句也涉及其中。您可以使用sp_getapplock确保这些插入连续发生

希望这有帮助

问候,

你最好在问这个问题，因为这不是一个编程问题。好运气，为什么服务器出现故障？在这方面会更好|
