When I started, the hardest part wasn't SQL syntax. It was translating things like "can you pull repeat buyers by region?" into the right joins, filters and edge cases (cancelled orders, date ranges, duplicates).

I made a free simulator that recreates that: stakeholder emails, real schemas, a PostgreSQL sandbox, and levels that go from a tiny startup to a global corp. Demo video is attached.

I'd love to hear how you practiced this skill, and whether something like this would have helped you. Link in the comments if anyone wants to try it.
