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。
当前回答
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
(
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+'%'

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。
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
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。
你可以随时刷新,因为它是EXCEL,一切都可以很容易地操纵!
对阿斯坦德的回答略有改进。我喜欢把我的标准放在最上面,让它更容易日复一日地重用:
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)
这是你的解决方案: 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')
