查询Sqlserver数据库死锁的一个存储过程(转)
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 @@error insert into #temp_who_lock(spid,blk) select 0 ,blocked from ( select * from master..sysprocesses where blocked>0)a where not exists( select * from master..sysprocesses where a.blocked =spid and blocked>0) union select spid,blocked from master..sysprocesses where blocked>0 if @@error<>0 return @@error select @ count = count (*),@ index =1 from #temp_who_lock if @@error<>0 return @@error if @ count =0 begin select '没有阻塞和死锁信息' return 0 end while @ index <=@ count begin if 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, @blk dbcc inputbuffer(@spid) dbcc inputbuffer(@blk) end set @ index =@ index +1 end if @lock=0 begin set @ index =1 while @ index <=@ count begin 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 +1 end end drop table #temp_who_lock return 0 end GO |
在查询分析器中执行:
exec sp_who_lock
直到最后的结果为:
