我使用sp_who来获取数据库中所有进程的列表。这样更好，因为您可能需要检查要终止哪个进程。

declare @proc table(
    SPID bigint,
    Status nvarchar(255),
    Login nvarchar(255),
    HostName nvarchar(255),
    BlkBy nvarchar(255),
    DBName nvarchar(255),
    Command nvarchar(MAX),
    CPUTime bigint,
    DiskIO bigint,
    LastBatch nvarchar(255),
    ProgramName nvarchar(255),
    SPID2 bigint,
    REQUESTID bigint
)

insert into @proc
exec sp_who2

select  *, KillCommand = concat('kill ', SPID, ';')
from    @proc

结果 您可以使用KillCommand列中的命令来终止您想要的进程。

SPID    KillCommand
26      kill 26;
27      kill 27;
28      kill 28;

Adam建议的方法不起作用的原因是，在循环活动连接的时间内，可以建立新的连接，而您将错过这些连接。你可以使用下面的方法，它没有这个缺点:

-- set your current connection to use master otherwise you might get an error

use master
ALTER DATABASE YourDatabase SET SINGLE_USER WITH ROLLBACK IMMEDIATE 

--do you stuff here 

ALTER DATABASE YourDatabase SET MULTI_USER

试试这个:

ALTER DATABASE [DATABASE_NAME]
SET SINGLE_USER
WITH ROLLBACK IMMEDIATE

下面是如何在MS SQL Server Management Studio 2008(可能也适用于其他版本)中可靠地执行这类事情:

In the Object Explorer Tree, right click the root database server (with the green arrow), then click activity monitor. Open the processes tab in the activity monitor, select the 'databases' drop down menu, and filter by the database you want. Right click the DB in Object Explorer and start a 'Tasks -> Take Offline' task. Leave this running in the background while you... Safely shut down whatever you can. Kill all remaining processes from the process tab. Bring the DB back online. Rename the DB. Bring your service back online and point it to the new DB.

您可以使用SP_Who命令杀死所有使用您的数据库的进程，然后重命名您的数据库。

杀他，用火杀他。

USE master
go

DECLARE @dbname sysname
SET @dbname = 'yourdbname'

DECLARE @spid int
SELECT @spid = min(spid) from master.dbo.sysprocesses where dbid = db_id(@dbname)
WHILE @spid IS NOT NULL
BEGIN
EXECUTE ('KILL ' + @spid)
SELECT @spid = min(spid) from master.dbo.sysprocesses where dbid = db_id(@dbname) AND spid > @spid
END
