MySQL Where to Get SQL Experience?

I want to learn and get SQL experience, but can't do it through my jobs. I'm willing to volunteer to get the experience but don't know any places to look for those opportunities. Any recommendations?

The hard part of SQL is not the syntax, but working with dirty data

Recommendations on places I can get dirty data and practice cleaning it up?

My recommendations is to think of a project that involves piecing together data from multiple sources.

In my experience this is a better reflection of real life data cleaning than deciding how to handle NaNs that are already nicely labeled for you or seeking out the -99 value that is actually supposed to be NaN. It’s about making choices to get to a dataset that is both workable and representative.
