【问题描述】：
据我了解，我的查询结果未正确保存/转发。应该发生的是，对于每台服务器（svr01、svr03、svr05、svr06、svr08），我应该获取他们的操作系统、完整域名等。然后这些信息用于填充我的 SQL 数据库（Hal0Test）。但是，该信息永远不会被发送，我不知道如何解决这个问题。
我在我的 powershell 脚本中添加了一个小的 html 输出，以便在本地查看我的结果。 html 对我来说更容易打开，然后运行 SQL Server Management Studio 并刷新该程序。但我仍然希望将所有这些变量发送到数据库。
目标：更正重复问题并开始将该信息发送到我的 sql 数据库。如果你能帮助我，那就太棒了！

这里有很多信息，我不确定哪些部分实际上是相关的。问题仅与您的 SQL 查询有关吗？您在尝试插入表格时是否看到错误？

对此很抱歉，但我的问题是我的程序，正如您在图像中看到的那样，正在复制而不是从 5 台服务器中的每台服务器中获取信息。但我不知道为什么，因为在控制台中它正在从每个服务器中提取正确的信息。但似乎我的 ServerArray 没有正确存储结果。
