SQL查死锁进程，并结束死锁进程ID，如结束不掉可能是正被使用或占用，查找原因再Kill

--如果发现死锁进程ID  则可以使用  Kill SPID 的方式终止进程

CREATE Table #Who(spid int,
    ecid int,
    status nvarchar(50),
    loginname nvarchar(50),
    hostname nvarchar(50),
    blk int,
    dbname nvarchar(50),
    cmd nvarchar(50),
    request_ID int);

CREATE Table #Lock(spid int,
    dpid int,
    objid int,
    indld int,
    [Type] nvarchar(20),
    Resource nvarchar(50),
    Mode nvarchar(10),
    Status nvarchar(10)
);

INSERT INTO #Who
    EXEC sp_who active  --看哪个引起的阻塞，blk 
INSERT INTO #Lock
    EXEC sp_lock  --看锁住了那个资源id，objid 

DECLARE @DBName nvarchar(20);
SET @DBName='IRMManage'

SELECT #Who.* FROM #Who WHERE dbname=@DBName
SELECT #Lock.* FROM #Lock
    JOIN #Who
        ON #Who.spid=#Lock.spid
            AND dbname=@DBName;

--最后发送到SQL Server的语句
DECLARE crsr Cursor FOR
    SELECT blk FROM #Who WHERE dbname=@DBName AND blk<>0;
DECLARE @blk int;
open crsr;
FETCH NEXT FROM crsr INTO @blk;
WHILE (@@FETCH_STATUS = 0)
BEGIN;
    dbcc inputbuffer(@blk);
    FETCH NEXT FROM crsr INTO @blk;
END;
close crsr;
DEALLOCATE crsr;

--锁定的资源
SELECT #Who.spid,hostname,objid,[type],mode,object_name(objid) as objName FROM #Lock
    JOIN #Who
        ON #Who.spid=#Lock.spid
            AND dbname=@DBName
    WHERE objid<>0;

DROP Table #Who;
DROP Table #Lock;
