Redmine

activerecord-sqlserver-adapter 5.2.0.rc1 has been released on February 12.

activerecord-sqlserver-adapter 5.2.0 has been released on March 19.
https://github.com/rails-sqlserver/activerecord-sqlserver-adapter/blob/master/CHANGELOG.md#v520

Can anyone test if Redmine 4.0 works with MS SQL Server? Please note that you have to run bundle update to install the latest activerecord-sqlserver-adapter gem.

yeap, here's the release, it would be great if redmine latest version could be confirmed to work ok with sql server...

and update the note at http://www.redmine.org/projects/redmine/wiki/RedmineInstall#Supported-database-back-ends

Redmine 4.0 does not support SQL Server as of December 2018 because a dependent library activerecord-sqlserver-adapter does not support Rails 5.2 yet.

I tested it on SQL Server 2017 with these gems
activerecord-sqlserver-adapter (5.2.0)
tiny_tds (2.1.2-x64-mingw32)

it passes all tests, but unfortunatelly there's a problem with migrations due to this bug
https://github.com/rails-sqlserver/activerecord-sqlserver-adapter/pull/691

TinyTds::Error: The object 'DF_projects_description' is dependent on column 'description'.
087_change_projects_description_to_text.rb:5:in `up'

there might be an option to add a workaround in redmine, but it won't be pretty, so I would prefer to fix the problem in activerecord-sqlserver-adapter.

Is there any progress on this? I would definitely like to upvote this as I have clients on Sql Server. I would also be happy to test potential solutions in our dev environments.

sorry, no feedback from activerecord-sqlserver-adapter's maintainers yet

but you can test my (unofficial) patch by changing the Gemfile

  when /sqlserver/
    gem "tiny_tds", "2.1.2", :platforms => [:mri, :mingw, :x64_mingw]
    gem "activerecord-sqlserver-adapter", :git => 'https://github.com/ahorek/activerecord-sqlserver-adapter.git', :branch => 'constrains_bug', :platforms => [:mri, :mingw, :x64_mingw]

on my environment it passes all activerecord-sqlserver-adapter's tests and redmine's tests. Let us know if it works for you.

ok, try to change the Gemfile instead.

  when /sqlserver/
    gem "tiny_tds", "2.1.2", :platforms => [:mri, :mingw, :x64_mingw]
    gem "activerecord-sqlserver-adapter", :git => 'https://github.com/ahorek/activerecord-sqlserver-adapter.git', :branch => 'constrains_bug', :platforms => [:mri, :mingw, :x64_mingw]

One of the causes is that a dependent library activerecord-sqlserver-adapter does not support Rails 5.2 yet.

Hi,
any news about this? I would like to use the latest version of redmine with mssql on windows. As far as I understand the answers in this thread do not solve the problem and currently there is no way to get the latest version of redmine running on mssql?

BR,
Bob

officially no, by using an unofficial patch yes. (https://www.redmine.org/issues/30285#note-16)

I'm not the maintainer of the https://github.com/rails-sqlserver/activerecord-sqlserver-adapter gem, so there's nothing more I can do. The current state of development seems to be pretty dead.
