Top Regions by KPI Thresholds

MediumSQL · PostgreSQL

Problem

Write a query to identify top-performing regions based on specific KPI thresholds for Bolt.

Use the supplied region, KPI measurement, and threshold data. A region qualifies only when its average value meets or exceeds every defined KPI threshold.

Output

  1. One row per qualifying region with region_name, completion_rate, acceptance_rate, rides_completed, and kpis_met.
  2. Include only regions meeting all three thresholds.
  3. Order by kpis_met descending, then region_name ascending.
