我正在尝试使用以下脚本获取数据库数据源的连接字符串：

   $Analysis_Server = New-Object Microsoft.AnalysisServices.Server  
   $Analysis_Server.connect("$server") 

   $database = $Analysis_Server.Databases[7]
   $c = $database.DataSources[0].ConnectionString
   $c

什么都没有输出。

我试过这样调试：

$Analysis_Server.Databases

这将打印出服务器上的所有数据库

如果我索引它$Analysis_Server.Databases[]，它会打印索引的任何数据库（所以在我的情况下，7，打印 database8）

显然，数据库属性正在工作。

-------------更新：--------------

这是数据库在服务器中的外观

server1_Databses

以下是以下每一行的作用：

   $Analysis_Server.Databases

这打印出来

数据库

人们可以注意到的一件事是，由于某种原因，它们不是按照它们在分析服务器上的顺序打印出来的，如图所示……我不知道为什么会这样

这是这个命令打印出来的：

Analysis_Server.Databases[0]

数据库8

现在由于 index 0 工作，我们应该能够 index[1], [2]等...

所以以下

Analysis_Server.Databases[1] 
Analysis_Server.Databases[2]

印刷：

数据库 1 和 3

现在到连接字符串：

$Analysis_Server.Databases[0].DataSources[0].ConnectionString

打印出来：

连接超时=60；用户 ID=someID；数据源=10.10.10.10；持久安全信息=True

它似乎是 Database8 的连接字符串

很酷，那么我们也应该能够做到这一点：

$Analysis_Server.Databases[1].DataSources[0].ConnectionString

但是，没有打印！似乎打印的唯一索引是Databases[0]

这是$Analysis_Server.Databases[0].DataSources[0]打印的：

数据源0

我们应该能够对所有数据库做同样的事情

$Analysis_Server.Databases[1].DataSources[0]

$Analysis_Server.Databases[2].DataSources[0] ETC..

但什么都没有打印出来！

不是说我有你的答案，但我认为你可以使用另一种方法来获得你需要的东西，同时等待微软的支持。

我正在开发一个运行 SQL Server 2014 的 AX 2012 演示系统。它在同一个实例中具有多个 olap 数据库。我已经编辑了所有数据源以指向不同的数据库，以表明我们得到了正确的详细信息。

我在测试时安装了最新的 SQL Server PowerShell 模块。

Install-Module SqlServer -Force -Confirm:$false
Import-Module SqlServer

现在您应该有一个新的 PowerShell 提供程序，它使您能够像文件系统一样遍历 SQL Server

Get-PSProvider

Name                 Capabilities                                      Drives

Registry             ShouldProcess, Transactions                       {HKLM, HKCU}

Environment          ShouldProcess                                     {Env}
FileSystem           Filter, ShouldProcess, Credentials                {C, E, A, D...}
Function             ShouldProcess                                     {Function}
Variable             ShouldProcess                                     {Variable}
SqlServer            Credentials                                       {SQLSERVER}
Certificate          ShouldProcess                                     {Cert}
WSMan                Credentials                                       {WSMan}

有了它，您应该能够执行以下操作，这应该会产生正确的结果

我会说这应该可以让您继续前进，因为您现在可以相信您拥有正确的连接字符串详细信息。我与您的其他问题有关-这应该为您提供要生成的 alter 脚本的所有详细信息，因此您可以按照 SQL Server 对您的期望提供整个 alter 语句。

我只是多玩了一些东西，以确保我理解您所面临的问题。在同一个盒子上，仍然加载了最新的可用 SqlServer PowerShell 模块——我得到了这些结果。

现在我遍历每个数据库及其数据源，以显示连接字符串

您能否花点时间尝试安装最新的 SqlServer PowerShell 模块，看看这对您和您面临的问题是否有任何影响？
