Select first row for each group in PostgreSQL

Given a table seasons:

We want to find the rows containing the maximum number of points per team.

The expected output we want is:

From the SQL Editor, you can run a query like:

select distinct
  on (team) id,
  team,
  points
from
  seasons
order BY
  id,
  points desc,
  team;

The important bits here are:

• The desc keyword to order the points from highest to lowest.
• The distinct keyword that tells Postgres to only return a single row per team.

This query can also be executed via psql or any other query editor if you prefer to connect directly to the database.
