Maybe kick things off with a question? about sql

[GA-MEB]

Maybe also contextualize the SQL lesson vis-a-vis learning Rails?
"We're going to learn SQL not because you need to write a lot of SQL to build a Rails application - you don't - but because your Rails app will be manipulating SQL databases behind the scenes as you do things, and it's important to be able to understand what it's doing. It's also important for debugging, since you might need to take a look into the data tables underlying your application when chasing down an error."
