How to write a subquery to find max, calculate proportions, and transverse multiple tables

Walkthrough several examples of subqueries or inner queries with Workbench and the Sakila sample database. In some ways a subquery is similar to a JOIN, and whereas the JOIN belongs to the FROM clause, the subquery belongs to the WHERE clause generally. Although a subquery can be substituted for any expression legally.
