Give yourself 2 hours a day to study & practice SQL for at least 2 months. It'll require personal sacrifice.

LearnSQL has some great courses if you're looking for some structure.

Otherwise start with W3Schools to understand the syntax and how things work. Then build from there with more in depth courses.
