Unable to load adalsql.dll error when calling `Invoke-sqlcmd`

问题

I have VS2015 with SSDT installed, along with SSMS and the SqlServer PowerShell module (which includes the invoke-sqlcmd comand), and yet If I try to execute a query against an Azure SQL Data Warehouse like so:

invoke-sqlcmd  -Query "Select top 5 * from customer"  -ConnectionString "Server=tcp:my.database.windows.net,1433;Database=Customer;  Authentication=Active Directory Integrated; Encrypt=True; "

I get the following error:

invoke-sqlcmd : Unable to load adalsql.dll (Authentication=ActiveDirectoryIntegrated). Error code: 0x2. For more information, see

If I try and install adalsql.dll directly, I get a message stating that A higher version already exists and I can see the both versions of the dll can be found here:

 C:\Windows\SysWOW64\adalsql.dll
 C:\Windows\System32\adalsql.dll

and yet, invoke-sqlcmd cant find it. Any idea how to either (A) register the existing dll so invoke-sqlcmd can find it or (B) uninstall it so that it can be re-installed?

Incidentally, I am able to use Active Directory Authenticatoin with the 32-bit SQLCMD.exe, so I know the 32 bit dll is working fine. It's just the 64 bit dll that isn't loading properly...

回答1:

So, this problem vexed me as well. I'm unclear as to how it happened, but maybe it's just coincidence that it happened when I installed the latest version of SSMS. My fix was to:

Navigate to Add or Remove Programs
In the little search window type sql, or just go find: "Active Directory Authentication Library for SQL Server".

Note: This will not be in Windows' installed programs list if you have installed Visual Studio 2019. You can run the same installer by invoking MsiExec.exe /I{6BF11ECE-3CE8-4FBA-991A-1F55AA6BE5BF} from a command prompt.
Uninstall that little guy
Navigate here and download the latest ADAL library (pick x64):
https://www.microsoft.com/en-us/download/confirmation.aspx?id=48742
Just for kicks, reboot
Your stuff should now properly load adalsql.dll!

In my case culprit was VS 2019. It has newer version of ADALSQL package. For me it was at path "C:\ProgramData\Microsoft\VisualStudio\Packages\sql_adalsql,version=16.0.61903.25110,chip=x64,language=en-US", which I uninstalled and installed desired version to resolve the issue.

Hope this helps!

In my case, add/remove programs didn't show any installed instances of "Active Directory Authentication Library". Yet, trying to install the library would fail saying a newer version was installed.

I un-wedged myself by opening the registry editor (regedt32) and using the Find feature from

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer

looking for adalsql.

That got a hit with containing keys

DisplayName: Active Directory Authentication Library for SQL Server
DisplayVersion: 15.0.1300.359

along with, importantly, a path to the associated installer. For me it was something like c:\windows\installer\4c334521.msi. I ran that msi and was finally able to "uninstall". After that, running the installer from the 'library' link above finally worked.

回答4:

Or you if planned to upgrade SSMS in the time being, simply uninstall "Active Directory Authentication Library for SQL Server", and repair SSMS.

Next time you upgrade SSMS it won't broke anything. SSMS bring his own adalsql.dll, and know how to upgrade it when you upgrade SSMS. But if you had installed adalsql with something else (or using https://www.microsoft.com/en-us/download/confirmation.aspx?id=48742 ), SSMS is somehow broken.
