How to Order Results in WOQL

What you'll achieve By the end of this guide, you will know how to sort and order query results using WOQL.

Prerequisites: TerminusDB running on localhost:6363 with the Star Wars dataset cloned. If you haven't done this yet, follow the Explore a Real Dataset tutorial (Steps 1–2), or run:
curl -u admin:root -X POST http://localhost:6363/api/clone/admin/star-wars \
  -H "Content-Type: application/json" \
  -H "Authorization-Remote: Basic cHVibGljOnB1YmxpYw==" \
  -d '{"remote_url": "https://data.terminusdb.org/public/star-wars", "label": "Star Wars", "comment": "Star Wars dataset"}'

Ordering results using `order_by`

The order_by keyword will allow you to sort results.

Example: JavaScript

let v = Vars("person", "label", "eyes", "group");
limit(2)
.order_by(["eyes", "desc"])
.select(v.eyes, v.group)
.group_by(
  "eyes",
  ["label"],
  v.group,
  and(triple(v.person, "rdf:type", "@schema:People"),
      triple(v.person, "label", v.label),
      triple(v.person, "eye_color", v.eyes)))

This returns the first two results of people, who have a given eye color, sorted by eye color, in reverse order.

To get the alternative order, you can write:

Example: JavaScript

let v = Vars("person", "label", "eyes", "group");
limit(2)
.order_by(["eyes", "asc"])
.select(v.eyes, v.group)
.group_by(
  "eyes",
  ["label"],
  v.group,
  and(triple(v.person, "rdf:type", "@schema:People"),
      triple(v.person, "label", v.label),
      triple(v.person, "eye_color", v.eyes)))

Or simply:

Example: JavaScript

let v = Vars("person", "label", "eyes", "group");
limit(2)
.order_by("eyes")
.select(v.eyes, v.group)
.group_by(
  "eyes",
  ["label"],
  v.group,
  and(triple(v.person, "rdf:type", "@schema:People"),
      triple(v.person, "label", v.label),
      triple(v.person, "eye_color", v.eyes)))
