SQLServer 2008数据库查看死锁、堵塞的SQL语句

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。

--每秒死锁数量

[html] view plaincopyprint?

SELECT *

FROM sys.dm_os_performance_counters

WHERE counter_name LIKE 'Number of Deadlocksc%';

SELECT  *
FROM    sys.dm_os_performance_counters
WHERE   counter_name LIKE 'Number of Deadlocksc%';

--查询当前阻塞

[html] view plaincopyprint?

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

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

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。
