🏋️SQL practice day: five business questions
No new syntax today. A manager asks questions in plain English; your job is to translate them into SQL, check the answer, and say it back in a sentence.

- Combine WHERE, JOIN, GROUP BY and ORDER BY in one query
- Sanity-check results before trusting them
