SQL Server:过滤sp_who2的输出

Question

在SQL Server下,是否有一种简单的方法来过滤sp_who2的输出？例如,我想只显示某个数据库的行.

Answer 1

你可以试试像

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 ....

并根据您的需求进行过滤.

Answer 2

您可以 将结果保存到临时表中,但直接转到源表会更好master.dbo.sysprocesses.

这是一个返回几乎完全相同结果的查询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 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Activity MonitorCtrlAltA

一种方法是创建临时表:

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

我创建了以下脚本,
解决了发现问题使用DMV与任何数据库的活动连接在sql 2005,2008和2008R2下可以正常工作

以下脚本使用sys.dm_exec_sessions,sys.dm_exec_requests,sys.dm_exec_connections,sys.dm_tran_locks

Answer 5

对Astander的回答略有改进.我喜欢将我的标准放在最前面,让日复一日的重用更容易:

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

    --SET @SPID = 10
    --SET @Status = 'BACKGROUND'
    --SET @LOGIN = 'sa'
    --SET @HostName = 'MSSQL-1'
    --SET @BlkBy = 0
    --SET @DBName = 'master'
    --SET @Command = 'SELECT INTO'
    --SET @CPUTime = 1000
    --SET @DiskIO = 1000
    --SET @LastBatch = '10/24 10:00:00'
    --SET @ProgramName = 'Microsoft SQL Server Management Studio - Query'
    --SET @SPID_1 = 10
    --SET @REQUESTID = 0

    SET NOCOUNT ON 
    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
    SET NOCOUNT OFF
    SELECT  *
    FROM    @Table
    WHERE
    (@Spid IS NULL OR SPID = @Spid)
    AND (@Status IS NULL OR Status = @Status)
    AND (@Login IS NULL OR Login = @Login)
    AND (@HostName IS NULL OR HostName = @HostName)
    AND (@BlkBy IS NULL OR BlkBy = @BlkBy)
    AND (@DBName IS NULL OR DBName = @DBName)
    AND (@Command IS NULL OR Command = @Command)
    AND (@CPUTime IS NULL OR CPUTime >= @CPUTime)
    AND (@DiskIO IS NULL OR DiskIO >= @DiskIO)
    AND (@LastBatch IS NULL OR LastBatch >= @LastBatch)
    AND (@ProgramName IS NULL OR ProgramName = @ProgramName)
    AND (@SPID_1 IS NULL OR SPID_1 = @SPID_1)
    AND (@REQUESTID IS NULL OR REQUESTID = @REQUESTID)

Answer 6

与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。这是我与 SP_WHO2 具有类似输出的最佳选择

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。
