使用sqlserver作为数据库的应用系统,都避免不了有时候会产生死锁, 死锁出现以后,维护人员或者开发人员大多只会通过sp_who来查找死锁的进程,然后用sp_kill杀掉。利用sp_who_lock这个存储过程,可以很方便的知道哪个进程出现了死锁,出现死锁的问题在哪里.
创建sp_who_lock存储过程
CREATE procedure sp_who_lock as begin declare @spid int declare @blk int declare @count int declare @index int declare @lock tinyint set @lock=0 create table #temp_who_lock(id int identity(1,1),spid int,blk int)if @@error<>0 return @@errorinsert into #temp_who_lock(spid,blk)select 0 ,blockedfrom (select * from master..sysprocesses where blocked>0)awhere not exists(select * from master..sysprocesses where a.blocked =spid and blocked>0)union select spid,blocked from master..sysprocesses where blocked>0if @@error<>0 return @@errorselect @count=count(*),@index=1 from #temp_who_lockif @@error<>0 return @@errorif @count=0beginselect "没有阻塞和死锁信息"return 0endwhile @index<=@countbeginif exists(select 1 from #temp_who_lock a where id>@index and exists(select 1 from #temp_who_lock where id<=@index and a.blk=spid))begin set @lock=1 select @spid=spid,@blk=blk from #temp_who_lock where id=@index select "引起数据库死锁的是: "+ CAST(@spid AS VARCHAR(10)) + "进程号,其执行的SQL语法如下" select @spid, @blkdbcc inputbuffer(@spid) dbcc inputbuffer(@blk)endset @index=@index+1endif @lock=0beginset @index=1while @index<=@countbegin select @spid=spid,@blk=blk from #temp_who_lock where id=@index if @spid=0 select "引起阻塞的是:"+cast(@blk 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(@blk AS VARCHAR(10)) +"阻塞,其当前进程执行的SQL语法如下" dbcc inputbuffer(@spid)dbcc inputbuffer(@blk) set @index=@index+1endenddrop table #temp_who_lockreturn 0 end GO
在查询分析器中执行:
exec sp_who_lock
