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
