Day 9: Learning SQL to Get Hired

Welcome to Day 9 of my "Learning SQL to Get Hired" series!

Today, I’m working through an easy LeetCode SQL problem:
- #1251 Average Selling Price

What you'll learn:
- Using JOINs to combine data across tables
- Calculating weighted averages with SUM and COUNT
- Real-world patterns like finding average prices or sales metrics in business data

As always, I’m walking through my thought process, showing how I debug mistakes and explaining what I’d expect if this came up in an interview. Try it yourself and let me know how you solved it!
