How to display the result of SQL execution?

Question

Ruby on Rails

There is a very long request. I do not quite understand what it does - it is necessary to display its results in portions. It starts like this: Ends: Then, of course, this data is transmitted:
sql = <<-SQL
SQL

ActiveRecord::Base.connection.select_values(sql).map(&:to_i).uniq

Answer 1

<<-SQL ... SQL is a multiline form of writing SQL queries.
Execute the query: ActiveRecord::Base.connection.execute(sql)
ActiveRecord::Base.connection.select_values(sql).map(&:to_i).uniq - this code also executes the query, but takes only the values ​​of the first column (id' shniks?), converts them into numbers and removes duplicates.
And in order to break the query into parts and display it in parts, you need to know SQL and manually parse it.
