Question

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。

我曾尝试像这样调试：

$Analysis_Server.Databases

这将打印出服务器上的所有数据库

如果我为$Analysis_Server.Databases[]编制索引，它将打印被索引的任何数据库（因此，在我的情况下为7，则显示数据库8）

显然，“数据库”属性正在运行。

------------- 更新：--------------

这是数据库在服务器中的外观

以下各行的作用如下：

   $Analysis_Server.Databases

这将打印出

人们可能会注意到的一件事是由于某种原因，它们的打印顺序不像图片中的那样在分析服务器上的顺序...我不知道为什么会这样

这是该命令输出的内容：

Analysis_Server.Databases[0]

现在，由于索引0有效，因此我们应该能够索引[1], [2]，依此类推...

以下是

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

打印：

现在连接字符串：

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

打印出的

：

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

它似乎是Database8的连接字符串

很酷，所以我们也应该能够做到这一点：

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

但是，什么也没打印！唯一显示的索引是Databases[0]

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

我们应该能够对所有数据库执行相同的操作

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

$Analysis_Server.Databases[2].DataSources[0] 等。

但是什么也没打印！

Answer 1

并不是说我有答案，但是我认为您可以在等待Microsoft支持的同时使用另一种方法来获得所需的内容。

我正在运行AX 2012演示系统，该系统运行SQL Server2014。在同一实例中有多个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。

我在测试此产品时安装了最新的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，它使您能够像遍历文件系统一样遍历SQL Server

Get-PSProvider

Name                 Capabilities                                      Drives

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

有了这些，您应该能够执行以下操作，从而产生正确的结果

我想说，这应该可以帮助您，因为您现在可以相信自己拥有正确的连接字符串详细信息。我与您的另一个问题有关-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的要求提供整个alter语句。

Answer 2

我只是玩了一点，以确保我了解您面临的问题。在同一框上，仍然加载了最新的可用SqlServer PowerShell模块-我得到了这些结果。

PS C:\Users\Administrator> $Analysis_Server = New-Object Microsoft.AnalysisServices.Server
PS C:\Users\Administrator> $Analysis_Server.connect("AX2012R2A")
PS C:\Users\Administrator> $Analysis_Server.Databases

Demand Forecast ps                       Processed            ReadWrite
Demand Forecast Accuracy ps              Processed            ReadWrite

Dynamics AX initial                      Processed            ReadWrite

现在，我遍历每个数据库及其数据源，以显示连接字符串

PS C:\Users\Administrator> $Analysis_Server.Databases | ForEach-Object {$_.datasources}

                                                        Security=SSPI;Initial

                                                        Security=SSPI;Initial
                                                        Catalog=DatabaseName_5

只有一个衬里为您提供连接字符串而没有其他任何东西

PS C:\Users\Administrator> $Analysis_Server.Databases | ForEach-Object {$_.datasources | ForEach-Object {$_.ConnectionSt
ring}}
Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_4

您能不能花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影响？
