[Concept Class] Learn and Use SQL Queries Right Away

It was beyond my expectations. As mentioned in other reviews, I could hear some background noise during the lecture (at the beginning), but it became less audible as it went on. This is a lecture that can help you build confidence in SQL, and I recommend it to beginners. Thanks to Joe's lecture, I was able to build trust in Infraon, which I first encountered. Please continue to provide great lectures in the future! (I would be even more grateful if you could give me a discount)

I recently got a job and was studying SQL statements in a hurry, and this was a great help. It was easy to listen to even for non-majors. Do you have any plans to make a more in-depth lecture?!

I haven't touched data for several years except for one information system class while I was in college, so I'm satisfied with the fact that I've been able to build a basic understanding of SQL with concise and accurate explanations. I still have difficulty writing queries myself (because the company's data structure is complicated), but I think I've gained some literacy in reading queries that have already been written.

This is a great lecture to get started with SQL. It was a great help to me because it eliminated all the difficult details and made the content that I need for practical work easier :)

It was helpful to have subtitles at the beginning. I was able to focus more because I could practice along with the exercises.^^

This is a "practical lecture" that is good for quickly getting a feel for SQL. It is a magical lecture that you can review naturally while listening to the lecture. P.S. The instructor's pronunciation and tone are good.

It was very helpful, thank you so much~ I never thought of asking the development department for not only data, but also queries, thank you for the great advice!

I liked that you explained the parts that were mostly just explained as basic knowledge and passed over accurately! Thank you for explaining the parts that would make a non-major give up as soon as they started in an easy-to-understand wayㅜㅜ
