# 1459. Rectangles Area

<https://leetcode.com/problems/rectangles-area>

## Description

Table: `Points`

```
+---------------+---------+
| Column Name   | Type    |
+---------------+---------+
| id            | int     |
| x\_value       | int     |
| y\_value       | int     |
+---------------+---------+
id is the primary key for this table.
Each point is represented as a 2D coordinate (x\_value, y\_value).
```

Write an SQL query to report all possible **axis-aligned** rectangles with **non-zero area** that can be formed by any two points in the `Points` table.

Each row in the result should contain three columns `(p1, p2, area)` where:

* `p1` and `p2` are the `id`'s of the two points that determine the opposite corners of a rectangle.
* `area` is the area of the rectangle and must be **non-zero**.

Report the query in descending order by `area` first, then in ascending order by `p1`'s `id` if there is a tie, then in ascending order by `p2`'s `id` if there is another tie.

The query result format is in the following table:

```
Points table:
+----------+-------------+-------------+
| id       | x\_value     | y\_value     |
+----------+-------------+-------------+
| 1        | 2           | 7           |
| 2        | 4           | 8           |
| 3        | 2           | 10          |
+----------+-------------+-------------+
Result table:
+----------+-------------+-------------+
| p1       | p2          | area        |
+----------+-------------+-------------+
| 2        | 3           | 4           |
| 1        | 2           | 2           |
+----------+-------------+-------------+

The rectangle formed by p1 = 2 and p2 = 3 has an area equal to |4-2| * |8-10| = 4.
The rectangle formed by p1 = 1 and p2 = 2 has an area equal to |2-4| * |7-8| = 2.
Note that the rectangle formed by p1 = 1 and p2 = 3 is invalid because the area is 0.
