a CTE must be advanced because I'm confused.... I'll have to re-watch a bunch of times until I understand
@MavenAnalytics

Yes, CTEs are an advanced topic! To understand them, we recommend first getting a solid grasp of the Big 6 and then getting some more exposure to subqueries. 1. Our Big 6 video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-yg4ZhrjqYf8.html 2. Our SQL guided project video (subquery example starts at 17:52): ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JaUKDbCXMX4.html

Awesome tutorial, crystal clear a d concise. Well done. 1. CTE is elegant. I would go for CTE when the first query returns a table, and go for subquery when the result set of the first query goes into select or where clauses as sclares or list/tuple. 2. Can get access to the dataset used here. 3. I quickly took a glance. At your SQL trainning program and it seems you dive deep and cover quite a lot than most SQL trainning programs in the market. Please advise the rate. Thank u
