# Sorting Rows By Index

Welcome back to pgcasts, my name is Josh Branchaud. In this episode I am going to talk about a handy shortcut we can use when ordering rows in a select statement.

Let's say we have a users table:

```sql
create table users (
  id serial primary key,
  first varchar not null,

require 'date'
require 'minitest/autorun'

class TestMeme < MiniTest::Unit::TestCase

  def time_to_timestamp(now:)
    hours_in_seconds = now.strftime('%H').to_i * 3600
    minutes_in_seconds = now.strftime('%M').to_i * 60
    seconds = now.strftime('%S').to_i
