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
