This repository contains simple sets of codes that draw triangles in the form of ASCII art using MySQL. I cam across these codes on HackerRank and I thought it was a very strange concept to SQL to draw triangles with ASCII art. But then it became a challenging tasks and I learned to use information_schema.tables, a dummy table that exists in every MySQL session.
You can find the original problems and discussions from the following links:
Draw the Triangle 1: https://bit.ly/3ATG0WY Draw the Triangle 2: https://bit.ly/3oqjEam
The propblem #2 is simply the reverse version of the #1, however it imposes an additional logical step in the code.
Each set of the code also requires the user to create a user-defined variable using '@' assignment syntax. More information about user- and system-defined variables in MySQL with '@' assignment syntax can be found here: https://bit.ly/34A9oVV
