ConnectionString 属性不打印连接字符串

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

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（所以在我的例子中，7，打印数据库8）

很明显，数据库属性正在运行。

-------------更新：-------------

这是数据库在服务器中的样子

以下每一行的作用如下：

   $Analysis_Server.Databases

这会打印出

可以注意到的一件事是出于某种原因，它们不是按照图片中在分析服务器上的顺序打印出来的……我不知道为什么会这样

这是此命令打印出的内容：

Analysis_Server.Databases[0]

既然索引 0 起作用了，我们应该能够索引 [1], [2]，等等...

所以下面

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：

Connection Timeout=60;User Id=someID;Data Source=10.10.10.10;Persist Security Info=True

它似乎是 Database8 的连接字符串

太棒了，那么我们也应该能够做到这一点：

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

但是，没有打印任何内容！似乎打印的唯一索引是 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..

但没有打印任何内容！

在此处的 post 中找到：http://www.mrtsql.com/2011/03/powershell-updating-analysis-services.html

看看那个 post 中的这个函数是否能帮助你。

function UpdateDataSources()
{
   # Lets get our server name
   $SSASServerName="$env:ComputerName\" + $SSASInstanceName
   $MyConnection = New-Object("Microsoft.AnalysisServices.Server")
   $MyConnection.Connect($SSASServerName)
   # lets return the number of data sources
   [int]$DataSourcecount=$MyConnection.Databases[$DatabaseName].DataSources.count
   for ($count=0; $count -ne $DataSourcecount;++$count)
   {
     $MyCS=$MyConnection.Databases[$DatabaseName].DataSources[$count].ConnectionString
    $NewCS=setNewValue -MyCS $MyCS -Pattern "Data Source=" -ReplaceWith $DataSourceServer

     if ($PW.Length -ne 0)
     {
        $NewCS=setNewValue -MyCS $NewCS -Pattern "Password=" -ReplaceWith $PW
     }
     if ($UserName.length -ne 0)
     {
        $NewCS=setNewValue -MyCS $NewCS -Pattern "User ID=" -ReplaceWith $UserName
     }
     $MyConnection.Databases[$DatabaseName].DataSources[$count].ConnectionString=$NewCS
     # write the change back to SSAS
     $MyConnection.Databases[$DatabaseName].DataSources[$count].update()

     write-output $NewCS
     }
}

Answer 2

并不是说我有一个答案给你，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 AX 2012 演示系统，即运行 SQL Server 2014。它在同一个实例中有多个 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细节。

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 服务器

Get-PSProvider

Name                 Capabilities                                      Drives

Registry             ShouldProcess, Transactions                       {HKLM, HKCU}
Alias                ShouldProcess                                     {Alias}
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}

有了我们的帮助，您应该能够执行以下操作，这应该会产生正确的结果

我想说这应该能让您继续，因为您现在可以相信您拥有正确的连接字符串详细信息。我与您的其他问题相关 - 这应该为您提供要生成的更改脚本的所有详细信息，因此您可以按照 SQL 服务器对您的期望提供整个更改语句。

Answer 3

我只是稍微尝试了一下，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。

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

Name                                     State                Read-Write Mode

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

                                                        Catalog=DatabaseName_5

单行代码只提供连接字符串，仅提供连接字符串

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