⭐ A lecture recommended for those with basic SQL knowledge!!! A lecture that will help you level up your SQL skills to intermediate and advanced levels. ⭐ Also recommended for those who have forgotten intermediate and advanced SQL grammar and need a review. ⭐ Above all, the biggest advantage is that it's free!!! ⭐ You can learn important intermediate and advanced SQL techniques in less than an hour. ⭐ You can learn the essentials of Windows functions, ROLLUP functions, and other functions that are difficult to study on your own through the lecture. ⭐ A really recommended lecture!! Please listen to it:)
