Problem accessing SQL Server from PowerShell

Question

I'm trying to implement a backup management script i found at http://sev17.com/2011/03/restore-and-relocate-database-files-using-powershell/

The article says it depends on SQLPSX version 2.3.2.1 or higher - I have the most current version.

attempting to execute this line:

$server = get-sqlserver $sqlserver

results in:

New-Object : Cannot find type [Microsoft.SqlServer.Management.Common.ServerConnection]: make sure the assembly containing this type is loaded.
At C:\Users\...\Documents\WindowsPowerShell\Modules\sqlserver\SQLServer.psm1:68 char:24
+     { $con = new-object <<<<  ("Microsoft.SqlServer.Management.Common.ServerConnection") $sqlserver }

result of get-module -listAvailable

RE: SMO

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.ConnectionInfo") 
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO")
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SmoExtended") 

results:

New-Object : Cannot find type [Microsoft.SqlServer.Management.Common.ServerConnection]: make sure the assembly containing this type is loaded.

Solution 1

Make sure the Assembly containing the Microsoft.SqlServer.Management.Common.ServerConnection type (which I think is Microsoft.SqlServer.ConnectionInfo) is loaded first:

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.ConnectionInfo")

Solution 2

For me works with

Import-Module -Name SqlServer

It could stay in script NOTE:

• Windows Server 2016

• Before I have installed

Install-Module -Name SqlServer

• With [Reflection.Assembly]::LoadWithPartialName works only on windows 10 for me.

Does it produce any output? You should see some info about the assembly. If it doesn't produce any output then you don't have that assembly in your GAC, meaning it won't be able to load it and therefore won't be able to load the ServerConnection type, giving you the error above.
