SELECT    
        p2.`HOST` 被阻塞方host,
        p2.`USER` 被阻塞方用户,
        r.trx_id 被阻塞方事务id,    
        r.trx_mysql_thread_id 被阻塞方线程号,

        ) 等待时间,    
        r.trx_query 被阻塞的查询,    
        l.lock_table 阻塞方锁住的表,

        m.lock_data  被阻塞方事务锁定记录的主键值,  
        p.`HOST` 阻塞方主机,
        p.`USER` 阻塞方用户,
        b.trx_id 阻塞方事务id,    
        b.trx_mysql_thread_id 阻塞方线程号,
        b.trx_query 阻塞方查询,
        l.`lock_mode` 阻塞方的锁模式,
        l.`lock_type` "阻塞方的锁类型(表锁还是行锁)",
        l.`lock_index` 阻塞方锁住的索引,
        l.`lock_space` 阻塞方锁对象的space_id,

        l.lock_data 阻塞方事务锁定记录的主键值,         
      IF (p.COMMAND = 'Sleep', CONCAT(p.TIME,' 秒'), 0) 阻塞方事务空闲的时间

需要杀 b.trx_mysql_thread_id 阻塞方线程号
