如何通过SQL2005查看死锁存储过程sp_who_lock?

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。

调用方法:选中相应的数据库,执行exec sp_who_lock

USE [master]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO


CREATE procedure [dbo].[sp_who_lock] 
as 
begin 
declare @spid int, @bl int, @intTransactionCountOnEntry int, @intRowcount int, @intCountProperties int, @intCounter int 

create table #tmp_lock_who ( 
id int identity(1,1), 
spid smallint, 
bl smallint
) 

IF @@ERROR<>0 RETURN @@ERROR 

insert into #tmp_lock_who(spid,bl) select 0 ,blocked 
from (select * from sysprocesses where blocked>0 ) a 
where not exists(select * from (select * from sysprocesses where blocked>0 ) b 
where a.blocked=spid) 
union select spid,blocked from sysprocesses where blocked>0 

IF @@ERROR<>0 RETURN @@ERROR 
 
-- 找到临时表的记录数 
select @intCountProperties = Count(*),@intCounter = 1 
from #tmp_lock_who 

IF @@ERROR<>0 RETURN @@ERROR 

if @intCountProperties=0 
select '现在没有阻塞和死锁信息' as message 

-- 循环开始 
while @intCounter <= @intCountProperties 
begin 
-- 取第一条记录 
select @spid = spid,@bl = bl 
from #tmp_lock_who where Id = @intCounter 
begin 
if @spid =0 
   select '引起数据库死锁的是: '+ CAST(@bl AS VARCHAR(10)) + '进程号,其执行的SQL语法如下' 
else 
   select '进程号SPID:'+ CAST(@spid AS VARCHAR(10))+ '被' + '进程号SPID:'+ CAST(@bl AS VARCHAR(10)) +'阻塞,其当前进程执行的SQL语法如下' 
DBCC INPUTBUFFER (@bl ) 
end 

-- 循环指针下移 
set @intCounter = @intCounter + 1 
end 

drop table #tmp_lock_who 

return 0 
end
