Getting typed results from ActiveRecord raw SQL

Question

In Sequel, I can do:

irb(main):003:0> DB[\"select false\"].get
=> false

Which returns a false boolean. I\'d like to be able to do so

Answer 1

This works for me in rails 5

results = ActiveRecord::Base.connection.select_all(sql)
results.rows.map{ |row| Hash[results.columns.zip(row)] }

Gives nice results

[{"person1"=>563, "person2"=>564, "count"=>1},
 {"person1"=>563, "person2"=>566, "count"=>5},
 {"person1"=>565, "person2"=>566, "count"=>1}]
