SQL Server:筛选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? 比方说,我想只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 ....
并筛选你所需要的。
您可以将结果保存到临时表中 ,但直接转到master.dbo.sysprocesses
上的源代码会更好
我已经构造这个输出几乎完全相同的事情, sp_who2
生成,除了你可以很容易地添加ORDER BY
和WHERE
子句获得有意义的输出。
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
一种方法是创build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://sqlserver2005.databases.aspfaq.com/how-do-i-mimic-sp-who2.html
我创build了以下脚本,
这解决了使用DMV查找任何数据库的活动连接,这在sql 2005,2008和2008R2下运行
以下脚本使用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 ( s.[host_name], ' .' ), DBName = COALESCE ( DB_NAME(COALESCE ( r.database_id, t.database_id )), '' ), Command = COALESCE ( r.Command, r.wait_type, wt.wait_type, r.last_wait_type, '' ), LastBatch = COALESCE ( r.start_time, s.last_request_start_time ), ProgramName = COALESCE ( s.program_name, '' ) FROM sys.dm_exec_sessions s LEFT OUTER JOIN sys.dm_exec_requests r ON s.session_id = r.session_id LEFT OUTER JOIN sys.dm_exec_connections c ON s.session_id = c.session_id LEFT OUTER JOIN ( SELECT request_session_id, database_id = MAX(resource_database_id) FROM sys.dm_tran_locks GROUP BY request_session_id ) t ON s.session_id = t.request_session_id LEFT OUTER JOIN sys.dm_os_waiting_tasks wt ON s.session_id = wt.session_id LEFT OUTER JOIN sys.dm_os_tasks ot ON s.session_id = ot.session_id LEFT OUTER JOIN ( SELECT ot.session_id, CPU_Time = MAX(usermode_time) FROM sys.dm_os_tasks ot INNER JOIN sys.dm_os_workers ow ON ot.worker_address = ow.worker_address INNER JOIN sys.dm_os_threads oth ON ow.thread_address = oth.thread_address GROUP BY ot.session_id ) tt ON s.session_id = tt.session_id WHERE COALESCE ( r.command, r.wait_type, wt.wait_type, r.last_wait_type, 'a' ) >= COALESCE ( '', 'a' ) ) Select * from DBConn where DBName like '%'+@dbName+'%'
稍微改善了阿斯达的答案。 我喜欢把自己的标准放在首位,让日常工作变得更容易:
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 --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)
有很多好的sp_who3用户存储过程 – 我相信Adam Machanic做得非常好,AFAIK。
亚当称它是活跃的: http : //sqlblog.com/blogs/adam_machanic/archive/tags/Scripts/default.aspx
是的,通过将sp_who2的输出捕获到一个表中,然后从表中select,但是这样做不好。 首先,由于sp_who2尽pipe受欢迎,但是它是一个无证的程序,你不应该依赖无证的程序。 其次,因为所有sp_who2都可以从sys.dm_exec_requests和其他DMV获得,并且show可以被过滤,sorting,join以及可查询行集合带来的所有其他好东西。
一个非常简单的方法就是在EXCEL中创build一个ODBC链接并从那里运行SP_WHO2。
你可以刷新,只要你喜欢,因为它的EXCEL一切都可以轻松地操纵!
类似于KyleMit的答案,它可以直接selectSP_WHO2使用的表,尽pipe我认为它只需要dbo.sysprocesses表。
如果有人打开这个SP,它可以理解它做了什么。 这是我最好的select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) ;
在这个select,您可以select您需要的领域,并有你想要的顺序。
扩展的第一个和最好的答案…我已经在master数据库上创build了一个存储过程,然后您可以将parameter passing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
我可能会扩展它以通过参数添加一个命令,甚至杀死一个对手,所以它杀死所有连接到一个特定的数据
这是您的解决scheme: http : //blogs.technet.com/b/wardpond/archive/2005/08/01/the-openrowset-trick-accessing-stored-procedure-output-in-a-select-statement的.aspx
select * from openrowset ('SQLOLEDB', '192.168.xx\DATA'; 'user'; 'password', 'sp_who')
