SqlServer强制断开数据库已有连接的方法

在master数据库中执行如下代码

declare @i INT 
declare cur cursor for select spid from sysprocesses where db_name(dbid)= ''Your_Database_Name'  
open cur  
fetch next from cur into @i  
while @@fetch_status=0 
  begin exec('kill '+@i) 
  fetch next from cur into @i 
  end  
close cur  
deallocate cur
