ODBCAdapter

An ActiveRecord ODBC adapter. Master branch is working off of Rails 5.0.1. Previous work has been done to make it compatible with Rails 3.2 and 4.2; for those versions use the 3.2.x or 4.2.x gem releases.

This adapter will work for basic queries for most DBMSs out of the box, without support for migrations. Full support is built-in for MySQL 5 and PostgreSQL 9 databases. You can register your own adapter to get more support for your DBMS using the ODBCAdapter.register function.

A lot of this work is based on OpenLink's ActiveRecord adapter which works for earlier versions of Rails.

Installation

Ensure you have the ODBC driver installed on your machine. You will also need the driver for whichever database to which you want ODBC to connect.

Add this line to your application's Gemfile:

gem 'odbc_adapter'

And then execute:

$ bundle

Or install it yourself as:

$ gem install odbc_adapter

Usage

Configure your database.yml by either using the dsn option to point to a DSN that corresponds to a valid entry in your ~/.odbc.ini file:

development:
  adapter:  odbc
  dsn: MyDatabaseDSN

or by using the conn_str option and specifying the entire connection string:

development:
  adapter: odbc
  conn_str: "DRIVER={PostgreSQL ANSI};SERVER=localhost;PORT=5432;DATABASE=my_database;UID=postgres;"

ActiveRecord models that use this connection will now be connecting to the configured database using the ODBC driver.

Testing

To run the tests, you'll need the ODBC driver as well as the connection adapter for each database against which you're trying to test. Then run DSN=MyDatabaseDSN bundle exec rake test and the test suite will be run by connecting to your database.
