📢 [Course Update Notice] Upgraded in November 2025. (Last Updated: November 27, 2025)
Updates
- Changed practice platform from w3schools to solvesql for faster and more stable SQL practice
- Updated and added existing SQL practice problems (total of 25 practice problems in advanced level)
- Provided new SQL cheat sheet
- Enhanced window function section practice and exercises, and added advanced topic (Frame)
SQL theory lectures are abundant,
but why aren't there any lectures where you can build real skills by practicing problem-solving alongside learning?
Just as studying English grammar alone won't improve your conversational skills without actual practice,
you can't properly use SQL by only studying its syntax.
Welcome to the advanced class, having completed the SQL basics and intermediate courses!
👏👏(clap clap clap)👏👏
So far, you've learned the basic SQL syntax (joining multiple tables, performing group operations, etc.),
and from now on, we'll cover various SQL features for solving more complex and challenging problems.
Through the advanced course, you'll be able to develop the skills to efficiently handle various operations needed in practical work,
and you can also pursue in-depth learning through additional materials provided in the middle or at the bottom of the lectures.
Great job to all the students who have completed the course from basics to advanced level!

현재 현업에서 SQL을 사용하고 있는 중이고, 개념을 전반적으로 다시 정리하기 위해 기초반부터 고급까지 전 강의 정주행 하였습니다. 먼저 강의 내용 자체는 정말 알차고 여러모로 큰 도움이 된 것 같습니다. 다만, 각각의 강의 영상 별로 볼륨 크기가 계속 차이가 난다던가 영상 도입 및 마감부에서 편집이 깔끔하지 못했던 부분들은 강의의 퀄리티 및 완성도 측면에서 조금은 아쉬운 부분인 것 같기도 합니다. 또한 이번 고급 강의처럼 기초/중급 레벨에도 강의 자료가 별도로 첨부되어 있었으면 각 레벨 별로 완강 이후 복습을 할 때 좀 더 효율적일 것 같습니다. 해당 개선점들에 대한 의견은 주관적인 부분이라 앞으로 강의 제작해주실 때 가볍게 참고해주셨으면 합니다. 좋은 강의 만들어주셔서 진심으로 감사드리고, 앞으로 새롭게 신설될 강의들도 기대하겠습니다!
