	host = String('mydemoserver.postgres.database.azure.com')
	database = String('postgres')
    user = String('mylogin%40mydemoserver')

	# Initialize connection object.
    connection = PG::Connection.new(:host => host, :user => user, :dbname => database, :port => '5432', :password => password)
    puts 'Successfully created connection to database.'

    resultSet = connection.exec('SELECT * from inventory;')
    resultSet.each do |row|
