查看数据库发生死锁的具体对象

执行以下的存储过程：

SELECT CAST (
    REPLACE (
        REPLACE (
            XEventData.XEvent.value ('(data/value)[1]', 'varchar(max)'),
            '<victim-list>', '<deadlock><victim-list>'),
        '<process-list>', '</victim-list><process-list>')
    AS XML) AS DeadlockGraph
FROM (SELECT CAST (target_data AS XML) AS TargetData
    FROM sys.dm_xe_session_targets st
    JOIN sys.dm_xe_sessions s ON s.address = st.event_session_address
    WHERE [name] = 'system_health') AS Data
CROSS APPLY TargetData.nodes ('//RingBufferTarget/event') AS XEventData (XEvent)
    WHERE XEventData.XEvent.value('@name', 'varchar(4000)') = 'xml_deadlock_report';

　　得到的结果会以XML的方式返回作为结果集，双击可以查看详细的结果集

在结果集中会找到“ID”方面的节点：<inputbuf>，将得到的两个ID放到以下对应的地方可以查出具体发生死锁的对象

select OBJECT_NAME([Object Id],[Database Id])

查看锁的详细：

SELECT L.request_session_id AS SPID, 
	DB_NAME(L.resource_database_id) AS DatabaseName, 
	O.Name AS LockedObjectName,
