Many thanks to David Poole for his time and help in peer-reviewing this article (i.e. Levels 6, 7, and 8) :-D.

Thanks for another good article.

I am totally excited to find this great series, I need to get up to speed quickly on CLR and the security issues involved and your tutorial is exactly what I was looking for. I really appreciate the detailed, step-by-step instructions with explanations of ‘why’ things are done, as well.
To learn by doing, I’ve gone through the steps in Part 6 and 7 – but I’m running into an issue however – it looks like the SQL query for AssemblySecuritySetup-Part1of2.sql might be truncated? When I paste it into either MSVS editor, or SSMS, it is getting flagged by Intellisense with the error ‘Unclosed quotation mark after the character N’ (line 55) and ‘Incorrect syntax near end of file’ at the very end.
Here is what I have copied/pasted from AssemblySecuritySetup-Part1of2.sql. It looks OK in the article and also here, but not in VS or in SSMS.

Can you offer any help on resolving this? Am I supposed to insert something in the last line? It looks like there's an End missing, to me. But I don't completely understand what this script is doing, yet.
Or is there something else I have wrong that is causing this problem? I've been through the step a couple of times to make sure I haven't skipped anything with the same results. Thanks for any help you can give me -

Thanks for another good article.
I just realized that I never replied to this, and I apologize for that.
Thank you very much for those kind words. I am glad to hear that you are liking this Stairway series :-).
Take care,
Solomon..

Hi there. Thank you very much for that compliment. I very much appreciate hearing that you appreciate the detail that I put into these articles. It takes quite a bit of time and energy (hence why I am not done with the series yet) but I think it's all worth it if it increases the general level of understanding of SQLCLR among the community, such that people are more successful using it and use it more appropriately.
To learn by doing, I’ve gone through the steps in Part 6 and 7 – but I’m running into an issue however – it looks like the SQL query for AssemblySecuritySetup-Part1of2.sql might be truncated? When I paste it into either MSVS editor, or SSMS, it is getting flagged by Intellisense with the error ‘Unclosed quotation mark after the character N’ (line 55) and ‘Incorrect syntax near end of file’ at the very end.
That script is the first half (hence named "Part1of2") of what will get concatenated into a single SQL script, along with "Part2of2" and a fragment of a file that gets produced when you compile the Assembly (so it doesn't exist yet). So yes, those Intellisense errors are to be expected. At this point, all you need to do is save the script so that it exists to be concatenated in the PostBuild Event.
Please let me know if that does not work, or if you have additional questions.
Take care,
Solomon..

Thanks very much for your quick response! And your explanation makes sense and with looking closer I can see how that works. However, my deploy failed 🙁

Does this give you any clue as to what's wrong here? Again, thanks for your aid.

Thanks very much for your quick response! And your explanation makes sense and with looking closer I can see how that works. However, my deploy failed 🙁Here is the text of the output from the deploy:
SET @sql = N'
CREATE ASSEMBLY [' + @AssemblyName + N'] AUTHORIZATION [dbo]
-- Insert the result of the following command, found in _TempAssembly.sql, here:
-- FINDSTR /I /C:"FROM 0x" KeyInfo_Create.sql > _TempAssembly.sql FROM 0x4D5A90000300000004000000FFE6F7
Does this give you any clue as to what's wrong here? Again, thanks for your aid.

Hi again. This should be easy to fix. You are missing a return on that last comment line of the Part1of2 script. The lack of return caused the FROM 0x4D5A... to be tacked onto the end of that inline comment. Just edit the Part1of2 script and add a return to the end so that the last real line is an empty line. Then re-run the deploy.
Please let me know if that works or not.
Take care,
Solomon..

You are quite welcome. Glad to hear that it is all working. I will try to add a note to the article about making sure that there is a carriage return at the end of that final inline comment line.

I had the exact same issue. Thanks for the clarification!

Solomon,
I have successfully deployed some SQL CLR for EXTERNAL_ACCESS to allow Web service calls from SQL Server. Since I am a DBA and not a .Net programming expert, I asked for a code review from someone on my team who is. She pointed out that they had done a .Net application deployment some years ago, and they had signed the application with a .pfx file. They had a problem with the application about a year later because the certificate in the .pfx file had expired.
For my development and deployment process, I created a simple assembly that had one class with no members, and I had Visual Studio create a new .pfx file for it. For my real assemblies that I use for SQL CLR, I import that .pfx file into the project for signing. That way, once I have created the asymmetric key and login, all other assemblies based on that .pfx file will install and run.
I checked my .pfx file with "C:\Windows\System32\certutil.exe", and it has an expiration date about 9 months from now.
Question 1: Are my SQL CLR procedures and functions going to stop working 9 months from now?
Question 2: Will I be able to sign future assemblies after 9 months using that .pfx file?
Question 3: Is there a more permanent solution?
Sincerely,
Daniel

Hi there, Daniel. Good question, and actually this might be better suited to being asked in the SQLCLR area of the SQL Server Central forums, but for the moment I can say that while I don't have time to test this to give a definitive answer, I believe:
1) I doubt anything will stop working as the public key should be usable forever
2) It is quite likely that you will not be able to sign future assemblies past the expiration date
3) The solution is to specify an end-date when creating the Certificate. The default end-date is 1 year from the creation date, but any means of generating a certificate will have an option for specifying the end date. Just pick something towards the upper-end, such as in 2099.
All of that being said, are you sure you created a certificate? If you created it via Visual Studio, in Project Properties, under "signing", then that should just be a strong name key file ("snk", which turns into "pfx" when protected with a password), and which does not have an expiration date.
------------------------------------
UPDATE:
This question was cross-posted on social.msdn.com, but that version contained some additional info. In that other version of the question it was stated that the .pfx file was created by Visual Studio and that it was an Asymmetric Key that was created in SQL Server. In this case, I can say that there is no issue here; there is no expiration date. Visual Studio does not deal with Certificates, and Asymmetric Keys in SQL Server do not have an expiration date.

Hi Solomon
Thank you for sharing this series.
I receive an error when deploying. Seems to happen when the assembly should be created.
Do you have any clues?

Hi Solomon
Thank you for sharing this series.
You are quite welcome 🙂

Ah, that is a SQL Server 2017 and newer problem. Please see the following post of mine for an updated version that accounts for the new security "feature":

Take care,
