🚀 SQL Challenge #14 — The Lift Capacity Problem is LIVE!
You’re given two tables — LIFT and LIFT_PASSENGERS.
Multiple passengers can try to enter the same lift, but the total passenger weight cannot exceed the lift’s capacity.
Your task?
👉 Write an SQL query that returns a comma-separated list of passengers who can fit into each lift without exceeding capacity, ordered by their weight in ascending order.
In this video, I’ll walk you through my entire step-by-step solution in SQL Server, breaking down the logic clearly so you can learn, understand, and apply it in your own interviews 💼
