SQL refreshing, is it helpful?

Question

I completed the sql course and got certified via sololearn. I want to get a job in this field but can't remember anything I studied. I don't want to go back over the course, but I might have to. Thoughts please...

Answer 1

Create your own project, that uses MySQL (which is free).

Start with a simple project, like a basic library system, where you store books by Title, Author, ISBN, Publisher, Year etc, and allow searching of books by those different terms.

Answer 2

Think about this.... If you want learn more is not enought just pick in the símbols and understand the lessons. You must practice... Sometimes one learns with a project based practice... Remember, practice makes the teacher in... 😀
