Shortest Distance in a Plane LeetCode Solution

Problem Statement

Table point_2d holds the coordinates (x,y) of some unique points (more than two) in a plane.

Write a query to find the shortest distance between these points rounded to 2 decimals.

The shortest distance is 1.00 from point (-1,-1) to (-1,2). So the output should be:

Note: The longest distance among all the points is less than 10000.
