SQLServer 2008数据库查看死锁、堵塞的SQL语句

查看那个表死锁

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

 

死锁和堵塞一直是性能测试执行中关注的重点。

下面是我整理的监控sql server数据库，在性能测试过程中是否出现死锁、堵塞的SQL语句，还算比较准备，留下来备用。

 1 --每秒死锁数量
 2 
 3 SELECT  *
 4 FROM    sys.dm_os_performance_counters
 5 WHERE   counter_name LIKE 'Number of Deadlocksc%';
 6 
 7 --查询当前阻塞
 8 
 9 WITH    CTE_SID ( BSID, SID, sql_handle )
10           AS ( SELECT   blocking_session_id ,
11                         session_id ,
12                         sql_handle
13                FROM     sys.dm_exec_requests
14                WHERE    blocking_session_id <> 0
15                UNION ALL
16                SELECT   A.blocking_session_id ,
17                         A.session_id ,
18                         A.sql_handle
19                FROM     sys.dm_exec_requests A
20                         JOIN CTE_SID B ON A.SESSION_ID = B.BSID
21              )
22     SELECT  C.BSID ,
23             C.SID ,
24             S.login_name ,
25             S.host_name ,
26             S.status ,
27             S.cpu_time ,
28             S.memory_usage ,
29             S.last_request_start_time ,
30             S.last_request_end_time ,
31             S.logical_reads ,
32             S.row_count ,
33             q.text
34     FROM    CTE_SID C 
35             JOIN sys.dm_exec_sessions S ON C.sid = s.session_id
36             CROSS APPLY sys.dm_exec_sql_text(C.sql_handle) Q
37     ORDER BY sid

在压力测试过程中，不间断的按F5键执行上面的SQL语句，如果出现死锁或者堵塞现象，就会在执行结果中罗列出来。如果每次连续执行SQL，都有死锁或者堵塞出现，说明死锁或者堵塞的比较严重。
