SQL 死鎖進程查看與處理

編輯:關於SqlServer


use   master   --必須在master數據庫中創建  
  go  
   
  if   exists   (select   *   from   dbo.sysobjects   where   id   =   object_id(N'[dbo].[p_lockinfo]')   and   OBJECTPROPERTY(id,   N'IsProcedure')   =   1)  
  drop   procedure   [dbo].[p_lockinfo]  
  GO  
   
  /*--處理死鎖  
   
    查看當前進程,或死鎖進程,並能自動殺掉死進程  
   
    因為是針對死的,所以如果有死鎖進程,只能查看死鎖進程  
    當然,你可以通過參數控制,不管有沒有死鎖,都只查看死鎖進程
