Sql Server查看死锁及堵塞脚本

--每秒死锁数量

SELECT  *
FROM sys.dm_os_performance_counters
WHERE counter_name LIKE 'Number of Deadlocksc%'; --查询当前阻塞 WITH CTE_SID ( BSID, SID, sql_handle )
AS ( SELECT blocking_session_id ,
session_id ,
sql_handle
FROM sys.dm_exec_requests
WHERE blocking_session_id <> 0
UNION ALL
SELECT A.blocking_session_id ,
A.session_id ,
A.sql_handle
FROM sys.dm_exec_requests A
JOIN CTE_SID B ON A.SESSION_ID = B.BSID
)
SELECT C.BSID ,
C.SID ,
S.login_name ,
S.host_name ,
S.status ,
S.cpu_time ,
S.memory_usage ,
S.last_request_start_time ,
S.last_request_end_time ,
S.logical_reads ,
S.row_count ,
q.text
FROM CTE_SID C
JOIN sys.dm_exec_sessions S ON C.sid = s.session_id
CROSS APPLY sys.dm_exec_sql_text(C.sql_handle) Q
ORDER BY sid

  

1,查看哪个表死锁

select object_name(resource_associated_entity_id) as tableName, request_session_id as pid from sys.dm_tran_locks
where resource_type = 'OBJECT'

2,结束死锁的进程

kill 70
