SQL for Top Sales Reps

MediumSQL · PostgreSQL

Problem

Write a SQL query to find the top 5 sales reps by closed-won revenue, excluding deals that were discounted by more than 20% at Appzen.

Use the sales_reps and deals tables. Treat a NULL discount as 0% and include only deals with status Closed Won.

Output

  1. One row per qualifying sales rep with rep_name and closed_won_revenue.
  2. Include the five highest-revenue reps, ordered by revenue descending, with rep_name ascending as the tie-breaker.
