2. Get to know the tables – contest_score
Summary

Instruction

Let's first get to know the tables that we'll use in this part of the course.

Our examples will be based on a table named contest_score. You can check its contents using the button on the right side of the screen.

This table is used in a TV show in which contestants are given points for tasks in two categories: physical (Workout) and intellectual (Knowledge). scores from 1 to 10 are given over the course of five weeks to five contestants.

This table has the following columns: full_name, week, category, and score.

Exercise

Select all information from the contest_score table.
