SQL Server:过滤sp_who2的输出

在SQL Server下，是否有一种简单的方法来过滤sp_who2的输出?例如，假设我只想显示某个数据库的行。

基于http://web.archive.org/web/20080218124946/http://sqlserver2005.databases.aspfaq.com/how-do-i-mimic-sp-who2.html 我已经创建了以下脚本，它解决了使用DMV在sql 2005, 2008和2008R2下查找到任何数据库的活动连接

以下脚本使用sys. sys。Dm_exec_sessions, sys。Dm_exec_requests, sys。Dm_exec_connections, sys.dm_tran_locks

这是你的解决方案: http://blogs.technet.com/b/wardpond/archive/2005/08/01/the-openrowset-trick-accessing-stored-procedure-output-in-a-select-statement.aspx

select * from openrowset ('SQLOLEDB', '192.168.x.x\DATA'; 'user'; 'password', 'sp_who')

我做了改进，不仅得到了被阻塞的进程，还得到了阻塞的进程:

DECLARE @Table TABLE
    (
    SPID INT, Status VARCHAR(MAX), LOGIN VARCHAR(MAX), HostName VARCHAR(MAX), BlkBy VARCHAR(MAX), DBName VARCHAR(MAX), Command VARCHAR(MAX), CPUTime INT, DiskIO INT, LastBatch VARCHAR(MAX), ProgramName VARCHAR(MAX), SPID_1 INT, REQUESTID INT
    )

INSERT INTO @Table EXEC sp_who2

SELECT  *
FROM    @Table
WHERE
    BlkBy not like '  .'
    or
    SPID in (SELECT  BlkBy from @Table where BlkBy not like '  .')

delete from @Table

是的，通过将sp_who2的输出捕获到表中，然后从表中进行选择，但这是一种糟糕的方式。首先，尽管sp_who2很流行，但它是一个没有文档的过程，您不应该依赖于没有文档的过程。其次，因为所有sp_who2可以做的事情，以及更多的事情，都可以从sys。dm_exec_requests和其他dmv，以及show可以过滤、排序、联接以及可查询行集附带的所有其他功能。

您可以将结果保存到临时表中，但是在master.dbo.sysprocesses上直接访问源代码会更好。

下面的查询将返回与sp_who2几乎完全相同的结果:

SELECT  spid,
        sp.[status],
        loginame [Login],
        hostname, 
        blocked BlkBy,
        sd.name DBName, 
        cmd Command,
        cpu CPUTime,
        physical_io DiskIO,
        last_batch LastBatch,
        [program_name] ProgramName   
FROM master.dbo.sysprocesses sp 
JOIN master.dbo.sysdatabases sd ON sp.dbid = sd.dbid
ORDER BY spid

现在，您可以轻松添加任何ORDER BY或WHERE子句，以获得有意义的输出。

或者，您也可以考虑在SSMS中使用活动监视器(Ctrl + Alt + A)
