My only question would be when in the turtorial, he mentions "But for the purposes of this tutorial I will use a table called ‘numbers’ and it will have two columns one called ‘number’ type int and the other one called ‘id’ type int, auto-incremented."
When he says it’s called numbers, does he mean the table has a class or id? And would would either change how it’s written in the script? He also names his 2 columns number and id. What if you have three columns? How does that change the code?
