SQLServer2008查看死鎖的存儲過程的代碼示例
在SQL Server 2008數(shù)據(jù)庫中，查看死鎖可以用存儲過程來實現(xiàn)，本文我們主要就介紹了SQL Server 2008查看死鎖的存儲過程的代碼示例，希望能夠?qū)δ兴鶐椭?/p>
代碼示例如下：
- if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[sp_who_lock]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
- drop procedure [dbo].[sp_who_lock]
- GO
- use master
- go
- create procedure 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
- -- 找到臨時表的記錄數(shù)
- select @intCountProperties = Count(*),@intCounter = 1
- from #tmp_lock_who
- IF @@ERROR<>0 RETURN @@ERROR
- if @intCountProperties=0
- select '現(xiàn)在沒有阻塞和死鎖信息' as message
- -- 循環(huán)開始
- while @intCounter <= @intCountProperties
- begin
- -- 取第一條記錄
- select @spidspid = spid,@blbl = bl
- from #tmp_lock_who where Id = @intCounter
- begin
- if @spid =0
- select '引起數(shù)據(jù)庫死鎖的是: '+ CAST(@bl AS VARCHAR(10)) + '進程號,其執(zhí)行的SQL語法如下'
- else
- select '進程號SPID：'+ CAST(@spid AS VARCHAR(10))+ '被' + '進程號SPID：'+ CAST(@bl AS VARCHAR(10)) +'阻塞,其當前進程執(zhí)行的SQL語法如下'
- DBCC INPUTBUFFER (@bl )
- end
- -- 循環(huán)指針下移
- set @intCounter = @intCounter + 1
- end
- drop table #tmp_lock_who
- return 0
- end
以上就是SQL Server 2008查看死鎖的存儲過程的代碼示例的全部內(nèi)容，本文我們就介紹到這里了，希望本次的介紹能夠?qū)δ兴斋@！
