Defined in:

Overview

This object contains one or more rows (a rowset). Enumerable is implemented so we can access the rows via the usual each, all, first, last.

first_row = response.results[0].first

Each row is a hash with the symbolized column names for keys.

puts first_row[:MY_COLUMN]

We can get a list of columns via schema.
