Track Customer Pain Points Monthly

MediumSQL · PostgreSQL

Problem

You are asked to build a simple recurring report that tracks customer pain points over time for athenahealth support activity. Write a PostgreSQL query that returns, for each month and pain point category, the number of distinct support cases, the number of distinct affected customers, and the share of that month’s cases represented by the category. Only include cases created in 2024 that are tied to an athenaOne customer account, and exclude cases with a null pain point category. The result should be sorted by month and then by case count descending within each month.
