I have an intermediate SQL knowledge, but I enjoyed this course. This will introduce a no code tool to generate the queries that it's fantastic.
You can achieve a decent level with this course, it's not long (around 2 hours) but the content is direct to the point. Probably the first time that I don't skip some chapters.
I have bought flySpeed tool, but you can use the free one, to follow this course.
I hope to see more courses from this guy!
