SQL SERVER 死锁查询存储

– exec sp_who_lock 查询哪个库的死锁，存储就建立在哪个库上

IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N’[dbo].[sp_who_lock]’) AND type in (N’P’, N’PC’))

DROP PROCEDURE [dbo].[sp_who_lock]

GO

– 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 N’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,@hostname = hostname

from #tmp_lock_who where Id = @intCounter

begin

if @spid =0

select N’引起数据库死锁的是:’ + CAST(@bl AS VARCHAR(10))+ N’进程号,主机名:’ + @hostname + N’其执行的SQL语法如下’

else

select N’进程号SPID：’+ CAST(@spid AS VARCHAR(10))+ N’被’ + N’进程号SPID：’+ CAST(@bl AS VARCHAR(10)) +N’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
