SELECT statements to retrieve data
Filtering queries using WHERE, AND, OR, IN, NOT IN, IS NULL, BETWEEN, LIKE, and DISTINCT
How to sort and group data using GROUP BY
How to order results with ORDER BY
How to use aliases for cleaner and more readable queries
A teaser into aggregating and summarizing data using COUNT and combinations of DISTINCT, GROUP BY, ORDER BY, and HAVING
