What exactly are you looking for? The example you posted returns
an array of hashes, but depending on what you're doing all that
work might not be necessary. PGconn#exec returns a PGresult object,
the PGresult#each iterator yields PGrow objects, and PGrow#[] accepts
both numeric and text indexes. Example:
% psql -d test -c 'SELECT id, name FROM people'id | name
----+------- 1 | Alice
(1 row)
% cat test.rb
require 'postgres'
conn = PGconn.new('dbname=test')
res = conn.exec('SELECT id, name FROM people')
res.each do |row| puts "by name: #{row['id']} #{row['name']}" puts "by position: #{row[0]} #{row[1]}"
end
res.clear
conn.close
% ruby test.rb
by name: 1 Alice
by position: 1 Alice
You could also convert the PGresult object into an array of PGrow
objects with a one-liner, although you wouldn't get automatic bytea
handling as in the function you posted:
rows = res.collect
Will any of this work for you? If not then please provide more
detail.
