在SQL Server下,是否有一种简单的方法来过滤sp_who2的输出?假设我只想显示某个数据库的行。

Answers:
您可以尝试类似
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。
您可以 将结果保存到临时表中,但是直接访问源会更好master.dbo.sysprocesses
。
这是一个查询,返回的结果几乎完全相同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,您可以轻松添加任何您喜欢的ORDER BY
or WHERE
子句,以获得有意义的输出。
另外,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

我创建了以下脚本,
该脚本可以解决查找问题使用DMV主动连接到任何数据库,在sql 2005、2008和2008R2下有效

稍微改善Astander的答案。我喜欢把我的标准放在首位,并使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
--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)
有很多不错的sp_who3用户存储过程-我确信Adam Machanic做的非常好,AFAIK。
亚当称它为活跃者:http: //whoisactive.com
与KyleMit答案类似,它可以直接选择SP_WHO2使用的表,尽管我认为它仅需要dbo.sysprocesses表。
如果有人打开此SP,它可以理解它的作用。这是我最好的选择,使输出与SP_WHO2类似
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。
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,并且因为它是EXCEL,所以一切都可以轻松操作!
是的,通过将sp_who2的输出捕获到表中,然后从表中进行选择,但这是一种不好的方法。首先,因为sp_who2尽管很流行,但是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,因为所有sp_who2都可以做很多事情,而且可以从sys.dm_exec_requests和其他DMV中获得更多信息,并且show可以被过滤,排序,加入以及所有其他可查询行集附带的东西。
扩展第一个和最佳答案...我已经在master数据库上创建了一个存储过程,然后可以将参数传递给..,例如数据库名称:
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甚至是杀死参数添加一个命令,这样它会杀死与特定数据的所有连接
这是为您提供的解决方案:http : //blogs.technet.com/b/wardpond/archive/2005/08/01/the-openrowset-trick-accessing-stored-procedure-output-in-a-select-statement .aspx
select * from openrowset ('SQLOLEDB', '192.168.x.x\DATA'; 'user'; 'password', 'sp_who')
