Not specifically a question, but just something I noted while watching this video: the BETWEEN
keyword is inclusive of the values. That is, we should think of it replacing the greater-than-or-equal-to >= and less-than-or-equal-to <=

WHERE something BETWEEN x AND y
is shorthand for:
WHERE something >= x AND something <= y
Not what you'd expect if you consider the word between literally! But I think SQL may have been created to appease accountants and not programmers.

Good to know though. Thanks for that. :)
