SQL Server數據庫阻塞，死鎖查詢

sql 查詢卡頓數據庫

SELECT SPID=p.spid,
       DBName = convert(CHAR(20),d.name),
       ProgramName = program_name,
       LoginName = convert(CHAR(20),l.name),
       HostName = convert(CHAR(20),hostname),
       Status = p.status,
       BlockedBy = p.blocked,
       LoginTime = login_time,
       QUERY = CAST(TEXT AS VARCHAR(MAX))
FROM   MASTER.dbo.sysprocesses p
       INNER JOIN MASTER.dbo.sysdatabases d
         ON p.dbid = d.dbid
       INNER JOIN MASTER.dbo.syslogins l
         ON p.sid = l.sid
       CROSS APPLY sys.dm_exec_sql_text(sql_handle)
WHERE  p.blocked = 0
       AND EXISTS (SELECT 1
                   FROM   MASTER..sysprocesses p1
                   WHERE  p1.blocked = p.spid)
