1、查詢當前正在執行的語句：

SELECT??

der.[session_id],der.[blocking_session_id],??

sp.lastwaittype,sp.hostname,sp.program_name,sp.loginame,??

der.[start_time] AS '開始時間',??

der.[status] AS '狀態',??

dest.[text] AS 'sql語句',??

DB_NAME(der.[database_id]) AS '數據庫名',??

der.[wait_type] AS '等待資源類型',??

der.[wait_time] AS '等待時間',??

der.[wait_resource] AS '等待的資源',??

der.[logical_reads] AS '邏輯讀次數'??

FROM sys.[dm_exec_requests] AS der??

INNER JOIN master.dbo.sysprocesses AS sp ON der.session_id=sp.spid??

CROSS APPLY? sys.[dm_exec_sql_text](der.[sql_handle]) AS dest??

--WHERE [session_id]>50 AND session_id<>@@SPID??

ORDER BY der.[session_id]??

GO

2、是否堵塞：

SELECT spid, blocked, waittime, waittype, waitresource

, p.dbid, cpu, physical_io, memusage, open_tran AS status

, login_time, last_batch, hostname, program_name, hostprocess

, loginame, cmd, text

FROM master.dbo.sysprocesses p

CROSS APPLY sys.dm_exec_sql_text(p.sql_handle) s

WHERE blocked > 0

OR spid IN (

SELECT blocked

FROM master.dbo.sysprocesses

WHERE blocked > 0

)

GO

3、是否有未提交事物：

SELECT spid, blocked, waittime, waittype, waitresource

, p.dbid, cpu, physical_io, memusage, open_tran

, status, login_time, last_batch, hostname, program_name

, hostprocess, loginame, cmd, text

FROM master.dbo.sysprocesses p

CROSS APPLY sys.dm_exec_sql_text(p.sql_handle) s

WHERE open_tran <> 0

GO

4、?死鎖：?

--drop table #deadlock

CREATE TABLE #deadlock(LogDate DATETIME,ProcessInfo VARCHAR(20),Text VARCHAR(2000))??

go??

INSERT INTO #deadlock EXEC xp_readerrorlog 0,1,'deadlock victim',NULL,'2016-07-20 14:00:00','2016-07-30','DESC'? ??

go
