I listened carefully. I'm sorry to say it's intermediate, but I think it's a bit basic. I expected to get a lot of tips from solving the problems after listening to the preview, but... I think those who have experience with SQL will think that it covers only the basics.. However, I think it will be a really useful and good lecture for those who have no experience with SQL!

[Practice Makes Perfect] Intermediate SQL for Data Analysis

DY, thank you for your course review. Since this is a lecture that follows the basic SQL class, I added the word intermediate, but it seems that the content is a bit different from what DY expected. If you want more in-depth content, I recommend solving the Medium problems on HackerRank and LeetCode :) The advanced SQL class that will be uploaded in March will cover slightly more difficult content such as subqueries, window functions, and regular expressions, so if you are interested, it would be a good idea to listen to it. Thank you^^
