视图中主要的字段：
1. Spid：Sql Servr 会话ID
2. Kpid：Windows  线程ID
3. Blocked：正在阻塞求情的会话 ID。如果此列为 Null，则标识请求未被阻塞
4. Waittype：当前连接的等待资源编号，标示是否等待资源，0 或 Null表示不需要等待任何资源
5. Waittime：当前等待时间，单位为毫秒，0 表示没有等待
6. DBID：当前正由进程使用的数据库ID
7. UID：执行命令的用户ID
8. Login_time：客户端进程登录到服务器的时间。
9. Last_batch：上次执行存储过程或Execute语句的时间。对于系统进程，将存储Sql Server 的启动时间
10.Open_tran：进程的打开事务个数。如果有嵌套事务，就会大于1
11.Status：进程ID 状态，dormant = 正在重置回话 ; running = 回话正在运行一个或多个批处理 ; background = 回话正在运行一个后台任务 ; rollback = 会话正在处理事务回滚 ; pending = 回话正在等待工作现成变为可用 ; runnable = 会话中的任务在等待获取 Scheduler 来运行的可执行队列中 ; spinloop = 会话中的任务正在等待自旋锁变为可用 ; suspended = 会话正在等待事件完成
12.Hostname：建立链接的客户端工作站的名称
13.Program_name：应用程序的名称，就是 连接字符串中配的 Application Name
14.Hostprocess：建立连接的应用程序在客户端工作站里的进程ID号
15.Cmd：当前正在执行的命令
16.Loginame：登录名
