Hello. I started a job that requires me to scrape and analyze data from a DB while using a different language. I took the beginner's course to learn and master the SQL language. Up until the intermediate course, it was an important lecture for me to organize what I had studied on my own and gain new information. And after reading the introduction to the advanced course you mentioned at the end, I thought it was a must-take class. I will definitely sign up for the advanced course when it comes out. I heard that you put a lot of effort into making a cheatsheet, so it will be very helpful. (I already sent you a request email. ^^;) Thank you for the great lecture.
