Ruby: Working with Postgres Database

Posted by Vivek on June 10, 2015

Firstly, install a ruby gem pg using the following command

gem install  pg

Then write a class to connect to database and retrieve values from a table

class PostGresClient

#!/usr/bin/env ruby

require ‘pg’

# Output a table of current connections to the DB
conn = PG.connect(“localhost”, 5432, , , “”, “”, “”)
res = conn.exec( “SELECT * FROM public.\”Employee\”)
res.each do |row|
row.each do |column|
puts column
