最強的sql server中查看連接數據的查詢語句

這個查詢很強吧.雖然sp_who也可以看到一些.但沒有統計.這個有統計.呵呵.當然,可以改成一個視圖.

select 


  CASE WHEN (GROUPING(hostname) = 1) THEN ＇_ALL＇ ELSE ISNULL(hostname, ＇UNKNOWN＇) END AS hostname,
       CASE WHEN (GROUPING(loginame) = 1) THEN ＇_ALL＇ ELSE ISNULL(loginame, ＇UNKNOWN＇) END AS loginame,count(*) as count_spid

 from master.dbo.sysprocesses with(nolock)
 where hostname<>＇＇
 group by hostname,loginame with cube
