快速排查SQL服务器阻塞语句

  SELECT*FROM sys.sysprocesses where spid>50 and blocked>0 --可以查看阻塞 
   
   
  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)  --可以查看阻塞的具体语句
