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
