Connect with Ruby on Rails

First, configure your SingleStore DB.

Open config/database.yml and edit the development adapter to use MySQL. You will need to have the SingleStore DB socket which can be found using the query show variables like 'socket'.

$ mysql -u root -h 127.1 -P 3306 -e "show variables like 'socket'"

+---------------+---------------------------------------------------------------------------------------+
| Variable_name | Value |
+---------------+---------------------------------------------------------------------------------------+
| socket | /var/lib/memsql-ops/data/installs/MI85eaf8fca04849888be7f1a9a596210e/data/memsql.sock |
+---------------+---------------------------------------------------------------------------------------+

SingleStore DB can run queries using the mysql2 connector in controller code. Calling execute returns a mysql2 result which can be converted to an array and easily displayed:

class WelcomeController < ApplicationController
  def index
    render plain: ActiveRecord::Base.connection.execute('show databases').to_a.join(' ')
  end
end
