A month and a half ago, with a lot of fanfare and maybe a little confetti, the SQL Server Tools Team released an update to SQL Server Management Studio that massively updated the SQL Server Powershell experience. As I blogged, this is a big deal and long overdue. I am extremely happy that this is finally getting some attention in Redmond.
However, once the dust settled and I had a chance to dig into things, I discovered that not all was rainbows and candy. The truth of the matter is that SQLPS is not so easily replaced. We are still going to be burdened with using the old module for at least the short term. This means at least being comfortable with the foibles of the old module.
Bundled With SSMS
The first real issue with the new SqlServer Powershell module is that is part of the SQL Server Management Studio install. I’ve long lamented the fact that you can’t install Powershell components separately. This means you’re limited to installing this only in locations where you can install SSMS 2016. Microsoft probably thinks you should be installing SSMS2016 EVERYWHERE, but even if you run on the bleeding edge this is a problem if you’re using Windows Server Core (no GUI, no SSMS).
I have not figured out any workaround to this. It’s possible to copy the module folder from a good install to somewhere else, but I’m nervous about that since something could be missed. This means that, until we can install this separately, users are stuck running SQLPS on servers without management studio. Yes, this means SQL 2016 without SSMS as well.
Not Recognized by SQL Agent
The second issue is that even if you do install SSMS 2016, SQL Agent won’t recognize and give you access to the new module if you use a PowerShell job step. When you create a PowerShell job step, the script in that job step runs within a specific context. It’s hidden from you, but whenever that script runs the first thing that happens is SQL Server launches sqlps.exe .
Sqlps.exe is a “mini-shell”, which configures a few things to support SQL Server and PowerShell together. The important piece here is that the executable is hard coded to use the SQLPS module. Now, sqlps.exe is deprecated and going away, but only in a future SQL Server release. This means if you’re using anything previous to this release (having no idea when the release will happen), you are going to be forced to use the SQLPS module if you are creating a Powershell script job step.
How can you get around this? This is a trick that’s been around for a while. I try to avoid it since it adds additional layers to running PowerShell in an agent job, but it does work. What you do is create a CmdExec agent job and call the Powershell executable to run your task. This approach gives you a LOT more control on how PowerShell is working in your environment, but takes some extra work . Hat tip: Derik Hammer ( @sqlhammer )
Stuck In The Past
Like I said before, I’m excited and happy the SQL Server Tools Team is improving the PowerShell experience for SQL Server. It has been a long time coming and I hope it continues. This is why it makes the above items SO frustrating, because while all these updates are being made, most of the user base won’t be able to use them. In a world where SQL Server installations still run on 2000 and 2005, it can take a long while to upgrade your core installation to take advantage of these improvements.
Normally, I’d be ok with this. I know that when I use an earlier version of SQL Server, I don’t get the shiny new toys. With SQLPS, though, it’s different. For all these years the experience has been klunky and problematic. While some of this klunky-ness finally got fixed back in March , most of us are still stuck with the workarounds because we do not have a way to install the updates.
What can you do about it? I’m glad you asked. Currently there are two Connect items that address these directly:
You can also make your voice heard on the community Trello board . As users, we’re at the mercy of Microsoft for updating this stuff and making it available to us. The goal is to raise awareness of these issues and let the development teams know how important they are. I will definitely give Microsoft credit for being more responsive to user feedback.
