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

Declare @dbName varchar(1000)
set @dbName='abc'

;WITH DBConn(SPID,[Status],[Login],HostName,DBName,Command,LastBatch,ProgramName)
As
(
SELECT 
    SPID = s.session_id,
    Status = UPPER(COALESCE
        (
            r.status,
            ot.task_state,
            s.status, 
        '')),
    [Login] = s.login_name,
    HostName = COALESCE
        (

                r.database_id,
                t.database_id
            )),
            ''
        ),
    Command = COALESCE

你可以试试

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 ....

过滤你需要的东西。

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。

有相当多好的sp_who3用户存储过程——我相信Adam Machanic做了一个非常好的存储过程，AFAIK。

一种方法是创建一个临时表:

CREATE TABLE #sp_who2 
(
   SPID INT,  
   Status VARCHAR(1000) NULL,  
   Login SYSNAME NULL,  
   HostName SYSNAME NULL,  
   BlkBy SYSNAME NULL,  
   DBName SYSNAME NULL,  
   Command VARCHAR(1000) NULL,  
   CPUTime INT NULL,  
   DiskIO INT NULL,  
   LastBatch VARCHAR(1000) NULL,  
   ProgramName VARCHAR(1000) NULL,  
   SPID2 INT
) 
GO

INSERT INTO #sp_who2
EXEC sp_who2
GO

SELECT *
FROM #sp_who2
WHERE Login = 'bla'
GO

DROP TABLE #sp_who2
GO
