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,例如。
答案 0 :(得分:312)
您可以尝试类似
的内容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 ....
并根据您的需要进行过滤。

你可以 save the results into a temp table,但直接转到master.dbo.sysprocesses
上的来源会更好。
此处的查询将返回与sp_who2
几乎完全相同的结果:
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想要的ORDER BY
或WHERE
子句,以获得有意义的输出。
或者,您可以考虑在SSMS中使用Activity Monitor( Ctrl + Alt + A )

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,它解决了使用DMV找到任何数据库的活动连接,这在sql 2005,2008和2008R2下工作
以下脚本使用sys.dm_exec_sessions,sys.dm_exec_requests,sys.dm_exec_connections,sys.dm_tran_locks

对Astander的回答略有改进。我喜欢把我的标准放在最前面,让日复一日地重复使用:
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 @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,

类似于KyleMit的答案,可以直接选择SP_WHO2使用的表格,虽然我认为它只需要dbo.sysprocesses表。
如果有人打开此SP,它可以理解它的作用。这是我最好选择与SP_WHO2
类似的输出@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private CustomAuthenticationProvider customAuthenticationProvider;
@Autowired
private RestAuthenticationEntryPoint restAuthenticationEntryPoint;
@Override
protected void configure(final AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(customAuthenticationProvider);
}
@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
@Override
protected void configure(final HttpSecurity http) throws Exception {
// @formatter:off
http
.csrf().disable()
.exceptionHandling()
.authenticationEntryPoint(restAuthenticationEntryPoint)
.and()
.authorizeRequests()
.antMatchers("/version/**").permitAll()
.anyRequest().hasAnyRole(Constants.ROLE_USER);
// @formatter:on
}
}
通过此选择,您可以选择所需的字段并获得所需的订单。

是的,通过将sp_who2的输出捕获到表中,然后从表中进行选择,但这样做是不好的方法。首先,因为sp_who2虽然很受欢迎,但它是一个无证的程序,你不应该依赖于无证件的程序。第二,因为所有sp_who2都可以从sys.dm_exec_requests和其他DMV获得,而且更多,并且show可以被过滤,排序,连接以及可查询行集所带来的所有其他好东西。

一种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,所有内容都可以轻松操作!

扩展第一个和最好的答案...我在master数据库上创建了一个存储过程,然后你可以将参数传递给..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
我可能会扩展它以通过参数或甚至杀死参数添加订单,以便它杀死所有与特定数据的连接
