除了你这一个操作应该不家其他的操作影响,不一定是因数你这个语句引起的。
给你一些语句自己检查一下吧
[code=sql]sp_who active --看看哪个引起的阻塞,blk
sp_lock --看看锁住了那个资源id,objid ,select object_name(objid) 得到
dbcc inputbuffer(@blk) -- 看看是那个语句[/code]
[code=sql] 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]
