如何在不删除服务器的情况下从命令提示符删除 SQL Server 2008 实例？

Question

我想删除一个 SQL Server 2008 实例（只是实例，而不是服务器）。我知道如何在 SQL Server 2005 中做到这一点，它的

"C:\Program Files\Microsoft SQL Server\90\SetupBootstrap\setup.exe" /QUIET /qb REMOVE=SQL_Engine,Client_Components INSTANCENAME=<INSTANCENAME>

但我不能在 2008 年做同样的事情。我试过：

"C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\SQLServer2008R2\setup.exe" /QS /Action=Uninstall /FEATURES=SQLEngine /INSTANCENAME=SQLEXPRESSAMEX

但它抛出：

错误结果：-2068643838
结果设施代码：1203
结果错误代码：2

使用这个摘要.txt：

我想我只是缺少一个选项或类似的选项，但我不知道是什么：P。

谢谢！

Answer 1

从 Jeremy 的评论中记录答案：

找到了：

"C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\SQLServer2008R2\setup.exe" /Action=Uninstall /INSTANCENAME=SQLEXPRESS /FEATURES=SQL,RS /QUIET

参数的顺序很重要。如果你先放 /QUIET 它会破坏它。此外，您不能只使用 SQLEngine 作为要删除的顶级功能。您需要指定 SQL & RS。
