Question

我在博客上找到了以下查询，但它仅获取受害者信息：

select top (1) with ties t1.*
from table1 t1 inner join
     table2 t2
     on t2.pid = t1.pid
order by row_number() over (partition by t2.pid order by t2.id desc);

现在，我想从资源列表中获取对象名称。我无法理解SELECT DATEADD(mi, DATEDIFF(mi, GETUTCDATE(), CURRENT_TIMESTAMP), DeadlockEventXML.value('(event/@timestamp)[1]', 'datetime2')) AS [EventTime], DeadlockEventXML.value('(//process[@id[//victim-list/victimProcess[1]/@id]]/@hostname)[1]', 'nvarchar(max)') AS HostName, DeadlockEventXML.value('(//process[@id[//victim-list/victimProcess[1]/@id]]/@clientapp)[1]', 'nvarchar(max)') AS ClientApp, DB_NAME(DeadlockEventXML.value('(//process[@id[//victim-list/victimProcess[1]/@id]]/@currentdb)[1]', 'nvarchar(max)')) AS [DatabaseName], DeadlockEventXML.value('(//process[@id[//victim-list/victimProcess[1]/@id]]/@transactionname)[1]', 'nvarchar(max)') AS VictimTransactionName, DeadlockEventXML.value('(//process[@id[//victim-list/victimProcess[1]/@id]]/@isolationlevel)[1]', 'nvarchar(max)') AS IsolationLevel, DeadlockEventXML.query('(event/data[@name="xml_report"]/value/deadlock)[1]') AS DeadLockGraph, DeadlockEventXML, CONVERT(DATE, GETDATE()) FROM (SELECT XEvent.query('.') AS DeadlockEventXML, Data.TargetData FROM (SELECT CAST(target_data AS XML) AS TargetData, CONVERT(DATE, GETDATE()) as InsertedDate FROM sys.dm_xe_session_targets st JOIN sys.dm_xe_sessions s ON s.address = st.event_session_address WHERE s.name = 'DeadLock' AND st.target_name = 'ring_buffer') AS Data CROSS APPLY TargetData.nodes('RingBufferTarget/event[@name="xml_deadlock_report"]') AS XEventData(XEvent)) AS DeadlockInfo声明。

我想获取死锁过程中包含的两个对象名。使用这种方法，我该如何获取它？

如何从扩展事件中获取对象名称？
