SQL2005查看死锁存储过程sp_who_lock

    下面是我整理的监控sql server数据库,在性能测试过程中是否出现死锁、堵塞的SQL语句,还算比较准备,留下来备用。

    调用方法:选中相应的数据库,执行exec sp_who_lock

    create table #tmp_lock_who ( 
    	id int identity(1,1), 
    	spid smallint, 
    	bl smallint
    )

    end 
    
    drop table #tmp_lock_who 
    
    return 0 
    end
