ConnectionString property not printing connection

问题:

I am trying to get the connection string of a database datasource with the following script:

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

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

nothing is outputting.

I have tried debugging like so:

$Analysis_Server.Databases

this prints out all databases on the server

if i index it $Analysis_Server.Databases[], it prints whatever database is indexed (so in my case, 7, prints database8)

clearly the Database property is working.

-------------UPDATE:--------------

here is how the Databases look in the server

here is what each of the following lines does:

   $Analysis_Server.Databases

this prints out

One thing one can notice is for some reason they are printed out not in order of how they are on the analysis server as in the picture...I dont know why that is the case

this is what this command prints out:

Analysis_Server.Databases[0]

Now since index 0 worked, we should be able to index [1], [2], etc...

so the following

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

prints:

Now unto the connection string:

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

that prints out:

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

its appears to be the connection string for Database8

cool, so then we should be able to do this as well:

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

However, nothing prints! the only index that seems to print is with Databases[0]

This is what $Analysis_Server.Databases[0].DataSources[0] prints:

we should be able to do the same for all databases

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

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

but nothing gets printed!

I just played with things a little more, to make sure I understood the issue that you are facing. On the same box, still with the newest available SqlServer PowerShell module loaded - I get these results.

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

Now I traverse every database and their datasources, to display the connection string

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

                                                        Catalog=DatabaseName_3

                                                        Security=SSPI;Initial
                                                        Catalog=DatabaseName_5

And the one-liner that just gives you the connection string and nothing else

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
Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_2
Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_1
Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_6
Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_3
Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_5

Could you take the time and try to install the latest SqlServer PowerShell module and see if that makes any difference for you and the problem that you are facing?

回答2:

Not saying that I have an answer for you, but I think you can use another approach to get what you need, while waiting for Microsoft support.

I'm working on a AX 2012 demo system, that is running SQL Server 2014. It has several olap databases inside the same instance. I've edited all datasources to point to a different database, to show that we get the correct details out.

I installed the latest SQL Server PowerShell module while testing this.

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

Now you should have a new PowerShell provider, that enables you to traverse the SQL Server as was it a file system

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}

With that in our hand, you should be able to do the following, that should produce the correct results

#Connect to the SSAS part of the sql server 
PS C:\Users\Administrator> cd SQLSERVER:\SQLAS

#List all local instances
PS SQLSERVER:\SQLAS> dir

I would say that this should get you going, because you can now trust that you have the correct connection string details. I relation to your other question - this should give you all the details for the alter script that you want to produce, so you supply the entire alter statement as the SQL Server expects from you.

See if this function in that post helps you out.
