我有一个以下的查询，我从一个人在工作中写的存储过程和我在互联网上找到的一些SQL。它可以在一个查询中获取服务器上的所有磁盘，可用空间以及数据库文件中的可用空间。
问题是我在自动化方面遇到了麻烦，并且撇号是正确的，这不是我的强项。有人可以帮助添加openrowset。理想情况下，我希望有一个表变量，其中有几个服务器，并从中传递服务器名称。
if exists ( select * from tempdb.dbo.sysobjects o
where o.xtype in ('U') and o.name in ('##DB_FILE_INFO' ))
drop table ##DB_FILE_INFO
if exists ( select * from tempdb.dbo.sysobjects o
