  • 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:

    SET QUOTED_IDENTIFIER ON
    GO
    SET ANSI_NULLS ON
    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
     
    -- 找到临时表的记录数
    select  @intCountProperties = Count(*),@intCounter = 1
    from #tmp_lock_who

    IF @@ERROR<>0 RETURN @@ERROR

    if @intCountProperties=0
      select '现在没有阻塞和死锁信息' as message

    -- 循环开始
    while @intCounter <= @intCountProperties
    begin
    -- 取第一条记录
      select  @spid = spid,@bl = bl
      from #tmp_lock_who where Id = @intCounter
    begin
      if @spid =0
                select '引起数据库死锁的是: '+ CAST(@bl AS VARCHAR(10)) + '进程号,其执行的SQL语法如下'
    else
                select '进程号SPID:'+ CAST(@spid AS VARCHAR(10))+ '被' + '进程号SPID:'+ CAST(@bl AS VARCHAR(10)) +'阻塞,其当前进程执行的SQL语法如下'
    DBCC INPUTBUFFER (@bl )
    end

    -- 循环指针下移
    set @intCounter = @intCounter + 1
    end

    drop table #tmp_lock_who

    return 0
    end

     

    GO
    SET QUOTED_IDENTIFIER OFF
    GO
    SET ANSI_NULLS ON
    GO

     

    p_killspid 如下:

    SET QUOTED_IDENTIFIER ON
    GO
    SET ANSI_NULLS ON
    GO

     

    create  proc p_killspid
    @dbname varchar(200)    --要关闭进程的数据库名
    as 
        declare @sql  nvarchar(500) 
        declare @spid nvarchar(20)

        declare #tb cursor for
            select spid=cast(spid as varchar(20)) from master..sysprocesses where dbid=db_id(@dbname)
        open #tb
        fetch next from #tb into @spid
        while @@fetch_status=0
        begin 
            exec('kill '+@spid)
            fetch next from #tb into @spid
        end 
        close #tb
        deallocate #tb


    GO
    SET QUOTED_IDENTIFIER OFF
    GO
    SET ANSI_NULLS ON
    GO

    SET QUOTED_IDENTIFIER ON
    GO
    SET ANSI_NULLS ON
    GO
