跟踪具体的死锁执行的影响的存储过程

不知道从哪里摘取的了

--sp_who和sp_who2来确定可能是哪些用户阻塞了其他用户,我们还可以用下面的存储过程来跟踪具体的死锁执行的影响:
create procedure 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
