SQL Server:过滤 sp_who2 的输出
在SQL Server下,有没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。
Under SQL Server, is there an easy way to filter the output of sp_who2? Say I wanted to just show rows for a certain database, for example.

您可以尝试类似的方法
并过滤您需要的内容。
You could try something like
And filter on what you require.
您可以保存将结果存入临时表,但最好直接转到
master.dbo.sysprocesses
上的源代码。这是一个查询,它将返回与
sp_who2
:现在您可以轻松添加任何您希望有意义的
ORDER BY
或WHERE
子句输出。或者,您可以考虑在 SSMS 中使用活动监视器 (Ctrl + Alt + A)
You could save the results into a temp table, but it would be even better to go directly to the source on
master.dbo.sysprocesses
.Here's a query that will return almost the exact same result as
sp_who2
:Now you can easily add any
ORDER BY
orWHERE
clauses you like to get meaningful output.Alternatively, you might consider using Activity Monitor in SSMS (Ctrl + Alt + A) as well
一种方法是创建临时表:
One way is to create a temp table:
基于 http://web.archive.org/web/20080218124946/http://sqlserver2005.databases.aspfaq.com/how-do-i-mimic-sp-who2.html
我创建了以下脚本,
它解决了使用 DMV 查找到任何数据库的活动连接的问题,这在 sql 2005、2008 和 2008R2 下工作
以下脚本使用 sys.dm_exec_sessions ,sys.dm_exec_requests 、 sys.dm_exec_connections , sys.dm_tran_locks
based on http://web.archive.org/web/20080218124946/http://sqlserver2005.databases.aspfaq.com/how-do-i-mimic-sp-who2.html
i have created following script ,
which resolves finding active connections to any datbase using DMV this works under sql 2005 , 2008 and 2008R2
Following script uses sys.dm_exec_sessions , sys.dm_exec_requests , sys.dm_exec_connections , sys.dm_tran_locks
对 Astander 的回答略有改进。我喜欢将我的标准放在首位,并使其更容易日常重用:
Slight improvement to Astander's answer. I like to put my criteria at top, and make it easier to reuse day to day:
类似于 KyleMit 答案,可以直接选择 SP_WHO2 使用的表,尽管我认为它只需要 dbo.sysprocesses 表。
如果有人打开这个SP,它就能明白它的作用。这是我最好的选择,具有与 SP_WHO2 类似的输出。
通过此选择,您可以选择所需的字段并具有所需的顺序。
Similar to KyleMit answer, its possible to select directly the tables used by SP_WHO2, although I think it's only need dbo.sysprocesses table.
If someone open this SP, it can understand what it does. This is my best select to have a similar output as SP_WHO2
Over this select, you can select the fields you need and have the order you want.
那里有很多很好的 sp_who3 用户存储过程 - 我确信 Adam Machanic 做得非常好,AFAIK。
Adam 将其称为“谁是活跃的”:

There's quite a few good sp_who3 user stored procedures out there - I'm sure Adam Machanic did a really good one, AFAIK.
Adam calls it Who Is Active:

第一个也是最佳答案的扩展...我在主数据库上创建了一个存储过程,然后您可以将参数传递给..例如数据库的名称:
我可能会扩展它以按参数添加订单,甚至是Kill paramatmer 因此它会终止与特定数据的所有连接
Extension of the first and best answer... I have created a stored procedure on the master database that you can then pass parameters to .. such as the name of the database:
I might extend it to add an order by parameter or even a kill paramatmer so it kills all connections to a particular data
是的,通过将 sp_who2 的输出捕获到表中,然后从表中进行选择,但这将是一个糟糕的方法。首先,因为 sp_who2 尽管很受欢迎,但它是一个未记录的过程,因此您不应该依赖未记录的过程。其次,因为 sp_who2 的所有功能以及更多功能都可以从 sys.dm_exec_requests 获取 和其他 DMV,并且可以对显示进行过滤、排序、连接以及可查询行集附带的所有其他功能。
Yes, by capturing the output of sp_who2 into a table and then selecting from the table, but that would be a bad way of doing it. First, because sp_who2, despite its popularity, its an undocumented procedure and you shouldn't rely on undocumented procedures. Second because all sp_who2 can do, and much more, can be obtained from sys.dm_exec_requests and other DMVs, and show can be filtered, ordered, joined and all the other goodies that come with queriable rowsets.
一种非常简单的方法是在 EXCEL 中创建 ODBC 链接并从那里运行 SP_WHO2。
您可以随时刷新,因为它是 EXCEL,所以一切都可以轻松操作!
A really easy way to do it is to create an ODBC link in EXCEL and run SP_WHO2 from there.
You can Refresh whenever you like and because it's EXCEL everything can be manipulated easily!
我做了一个改进,以便不仅可以获得阻塞进程,还可以获取阻塞进程:
I made an improvement in order to obtain not only the blocked processes but also the blocking process:
我写在这里是为了将来自己使用。它使用 sp_who2 并插入表变量而不是临时表,因为如果不删除临时表,则不能使用两次。
并在同一行显示被阻止和阻止者。
I am writing here for future use of my own. It uses sp_who2 and insert into table variable instead of temp table because Temp table cannot be used twice if you do not drop it.
And shows blocked and blocker at the same line.
这是适合您的解决方案:
This is the solution for you:
