The SQL Server adapter for ActiveRecord using SQL Server 2012 or higher. Interested in older versions? We follow a rational versioning policy that tracks Rails. That means that our 7.x version of the adapter is only for the latest 7.x version of Rails. If you need the adapter for SQL Server 2008 or 2005, you are still in the right spot. Just install the latest 3.2.x to 4.1.x version of the adapter that matches your Rails version. We also have stable branches for each major/minor release of ActiveRecord. For older versions, please check their stable branches. We support every data type supported by FreeTDS. All simplified Rails types in migrations will coorespond to a matching SQL Server national (unicode) data type. Always check the initialize_native_database_types (here) for an updated list. The following types (date, datetime2, datetimeoffset, time) all require TDS version 7.3 with TinyTDS. We recommend using FreeTDS 1.0 or higher which default to using TDSVER to 7.3. The adapter also sets TinyTDS's tds_version to this as well if non is specified. The Rails v5 adapter supports ActiveRecord's datetime_with_precision setting. This means that passing :precision to a datetime column is supported. Using a precision with the :datetime type will signal the adapter to use the datetime2 type under the hood. The adapter uses OUTPUT INSERTED so that we can select any data type key, for example UUID tables. However, this poses a problem with tables that use triggers. The solution requires that we use a more complex insert statement which uses a temporary table to select the inserted identity. To use this format you must declare your table exempt from the simple output inserted style with the table name into a concurrent hash. Optionally, you can set the data type of the table's primary key to return. Although it is not necessary, the Ruby convention is to use lowercase method names. If your database schema is in upper or mixed case, we can force all table and column names during the schema reflection process to be lowercase. Add this to your config/initializers file for the adapter. Depending on your user and schema setup, it may be needed to use a table name prefix of dbo.. So something like this in your initializer file for ActiveRecord or the adapter.

I worked through this with some more experienced Ruby devs when I was back at work and we came to the conclusion that this is an unhandled edge case in ActiveRecord (see below for more info).
My eventual workaround (with comments) is to override the existing method(s) in a concern and only include that concern when we need it:

You installed version
2.3.8 of the
activerecord-sqlserver-adapter gem that is almost 8 years old and tried to run it with the latest version of Ruby on Rails. Obviously, both versions are not compatible.
Furthermore, looking at the gem's Rubygem page - there is no version supporting Ruby on Rails 5.2 yet.
My advice is to downgrade your application to 5.1 and postpone updating to Rails 5.2 until all gems your application is depending on are supporting 5.2
You might want to subscript to these issues on GitHub for further updates:
When using ActiveRecord to store a string into a SqlServer nvchar column, and the length of the string is larger than the maximum length of the column, the string is silently truncated to the column's size. How can I make a warning or error be issued instead of silently truncating the value?Code that reproduces the issue
ANSWERAnswered 2017-Jul-20 at 13:49
In order to cause SqlServer to respond to a text overflow with an error, two things are required:
- SqlServer's ANSI_WARNINGS connection setting must be ON
- You must prevent the adapter from truncating the column.
Among the effects of the ANSI_WARNINGS setting is to abort an INSERT or UPDATE if a character column is overflowed. There is a setting that controls that effect:
If an INSERT or UPDATE is tried on a character, Unicode, or binary column in which the length of a new value exceeds the maximum size of the column. If SET ANSI_WARNINGS is ON, the INSERT or UPDATE is canceled as specified by the ISO standard.
This setting is probably already on, but you can force it on with this monkey-patch:

In the very beginning I was thinking that your problem was related to the availability of the gem for your current ruby version (something like this issue on GitHub).
Digging into the documentation of the gem, in order to install on win you should run
rake gem:windows first:
Compiling Gems for Windows
For the convenience of Windows users, TinyTDS ships pre-compiled gems for Ruby 2.0, 2.1, 2.2, and 2.3 on Windows. In order to generate these gems, rake-compiler-dock is used. This project provides a Docker image with rvm, cross-compilers and a number of different target versions of Ruby.
Run the following rake task to compile the gems for Windows. This will check the availability of Docker (and boot2docker on Windows or OS-X) and will give some advice for download and installation. When docker is running, it will download the docker image (once-only) and start the build:
$ rake gem:windows

So this was a weird problem. I had to migrate connection logic into the base classes. For some reason the second call to establish_connection was making AR4 "forget" the first establish_connection. this is weird since this was working on AR3. my models now look like this
