How to connect to sql server

[eamonnmcevoy]

I have tried installing tiny_tds, also tried activerecord-sqlserver-adapter but both give me the following error:

2019-10-14 07:21:34 +0000 [error]: #0 fluent/log.rb:362:error: Could not load the 'tiny_tds' Active Record adapter. Ensure that the adapter is spelled correctly in config/database.yml and that you've added the necessary adapter gem to your Gemfile. path=nil error_class=LoadError error="Could not load the 'tiny_tds' Active Record adapter.

Try changing the adapter to sqlserver. it works for me. this is only difference i have with my configuration.

@eamonnmcevoy - were you able to resolve this issue? I'm facing the similar for snowflake! I see you're using activerecord-sqlserver-adapter for sqlserver. so do you know if there any activerecord adapter available for snowflake?
