  • sql server 查看表的死锁和Kill 死锁进程

    查询出来

    select    
        request_session_id spid,   
        OBJECT_NAME(resource_associated_entity_id) tableName    
    from    
        sys.dm_tran_locks   
    where    
        resource_type='OBJECT  

    杀死死锁进程

    kill spid 

    另:

    exec master.dbo.sp_who_lock --查看当前死锁进程

    exec master.dbo.p_killspid ytsafety--杀掉引起死锁的进程

    sp_who_lock如下:
