在 SQL Server 下,有没有简单的方法来过滤 sp_who2 的输出?例如,假设我只想显示某个数据库的行。

你可以尝试类似的东西

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 ....

并过滤您需要的内容。

可以 将结果保存到临时表中,但最好直接转到源代码master.dbo.sysprocesses

这是一个查询,它将返回几乎完全相同的结果sp_who2

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,您可以轻松添加您喜欢的任何ORDER BYWHERE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CtrlAltA

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

基于http://web.archive.org/web/20080218124946/http://sqlserver2005.databases.aspfaq.com/how-do-i-mimic-sp-who2.html

对Astander 的回答略有改进。我喜欢把我的标准放在首位,让日常重用变得更容易:

DECLARE @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

KyleMit answer类似,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,它可以理解它的作用。这是我最好的选择,具有与 SP_WHO2 类似的输出

select convert(char(5),sp.spid) as SPID
        ,  CASE lower(sp.status)
                 When 'sleeping' Then lower(sp.status)
                 Else  upper(sp.status)
              END as Status
        , convert(sysname, rtrim(sp.loginame)) as LOGIN
        , CASE sp.hostname
                 When Null  Then '  .'
                 When ' ' Then '  .'
                 Else    rtrim(sp.hostname)
              END as HostName
        , CASE isnull(convert(char(5),sp.blocked),'0')
                 When '0' Then '  .'
                 Else isnull(convert(char(5),sp.blocked),'0')
              END as BlkBy
        , case when sp.dbid = 0 then null when sp.dbid <> 0 then db_name(sp.dbid) end as DBName
        , sp.cmd as Command
        , sp.cpu as CPUTime
        , sp.physical_io as DiskIO
        , sp.last_batch as LastBatch
        , sp.program_name as ProgramName 
        from master.dbo.sysprocesses sp (nolock)
  ;

通过此选择,您可以选择所需的字段并获得所需的顺序。

那里有很多好的 sp_who3 用户存储过程 - 我确信 Adam Machanic 做得非常好,AFAIK。

是的,通过将 sp_who2 的输出捕获到一个表中,然后从该表中进行选择,但这将是一种不好的做法。首先,因为 sp_who2 尽管很受欢迎,但它是一个未记录的过程,您不应该依赖未记录的过程。其次,因为 sp_who2 可以做的所有事情,甚至更多,都可以从sys.dm_exec_requests和其他 DMV 中获得,并且可以过滤、排序、加入 show 以及所有其他可查询行集附带的好东西。

一个非常简单的方法是在 EXCEL 中创建一个 ODBC 链接并从那里运行 SP_WHO2。

您可以随时刷新,因为它是 EXCEL,一切都可以轻松操作!

第一个也是最好的答案的扩展......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:

USE master
GO

CREATE PROCEDURE sp_who_db
(
    @sDBName varchar(200)   = null,
    @sStatus varchar(200)   = null,
    @sCommand varchar(200)  = null,
    @nCPUTime int           = null
)
AS
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   (@sDBName IS NULL OR DBName = @sDBName)
    AND     (@sStatus IS NULL OR Status = @sStatus)
    AND     (@sCommand IS NULL OR Command = @sCommand)
    AND     (@nCPUTime IS NULL OR CPUTime > @nCPUTime)
GO 

我可能会扩展它以按参数添加顺序,甚至添加一个终止参数,以便它终止与特定数据的所有连接

我进行了改进,以便不仅获得阻塞进程,还获得阻塞进程:

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

我写在这里是为了将来我自己的使用。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。并在同一行显示阻塞和阻塞。
