可以从 SQL Server 2008 中的环形缓冲区中提取的死锁 xml 创建图表吗？

Question

在 SQL_Server 的更高版本中，我们在对象浏览器中查看事件文件以查看死锁图。这个特定的客户端有 SQL 2008（兼容性 2005），并且使用以下脚本从环形缓冲区中提取了唯一的死锁副本：

SELECT
   xed.value('@timestamp', 'datetime2(3)') as CreationDate,
   xed.query('.') AS XEvent
FROM
(
   SELECT CAST([target_data] AS XML) AS TargetData
   FROM sys.dm_xe_session_targets AS st
   INNER JOIN sys.dm_xe_sessions AS s
      ON s.address = st.event_session_address
   WHERE s.name = N'system_health'
         AND st.target_name = N'ring_buffer'
) AS Data
CROSS APPLY TargetData.nodes('RingBufferTarget/event[@name="xml_deadlock_report"]') AS XEventData (xed)
ORDER BY CreationDate DESC

该格式与我们的 xdl 查看器不兼容。有没有办法从下面返回的 XML 中获取图表？：

<event name="xml_deadlock_report" package="sqlserver" id="123" version="1" timestamp="2018-07-04T00:15:14.667Z">
  <data name="xml_report">

    <value>&lt;deadlock&gt;

Answer 1

是的。这是嵌入在 XML 中的 XML，因此您需要使用如下查询来提取和解除死锁 XML：

select cast(@doc.value('(/event/data/value/.)[1]', 'nvarchar(max)') as xml) deadlock

然后在 SSMS 中打开 XML 结果并使用 .xdl 扩展名保存文件。然后用 SSMS 重新打开它，你会看到死锁图。
