Rails 3 execute custom sql query without a model

Question

I need to write a standalone ruby script that is supposed to deal with database. I used code given below in rails 3

@connection = ActiveRecord::Base.establis         


        

Answer 1

How about this :

@client = TinyTds::Client.new(
      :adapter => 'mysql2',
      :host => 'host',
      :database => 'siteconfig_development',
      :username => 'username',
      :password => 'password'

sql = "SELECT * FROM users"

result = @client.execute(sql)

results.each do |row|
puts row[0]
end

You need to have TinyTds gem installed, since you didn't specify it in your question I didn't use Active Record
