if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[p_killspid]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
         drop procedure [dbo].[p_killspid]
         GO

         create proc p_killspid
         @dbname varchar(200)   --要关闭进程的数据库名
         as  
            declare @sql  nvarchar(500)  
            declare @spid nvarchar(20)

            declare #tb cursor for
               select spid=cast(spid as varchar(20)) from master..sysprocesses where dbid=db_id(@dbname)
            open #tb
            fetch next from #tb into @spid
            while @@fetch_status=0
            begin  
               exec('kill '+@spid)
               fetch next from #tb into @spid
            end  
            close #tb
            deallocate #tb

代码中调用上面的存储过程
