Suggestion Required for Best SQL Courses

Hello this is Gulshan Negi
I am a Software Developer. Well, as a software developer, we know that SQL is an essential skill for anyone working with databases. Recently, I was looking for the best SQL courses and I found this post where the author listed the best 10 SQL courses, but it became overwhelming to choose the best one amongst them. Can anyone give their suggestions on this?
Hoping for some positive response.
