Top 5 Salaries SQL

MediumSQL · PostgreSQL

Problem

Tavant's ignio staffing dashboard needs a salary view for workforce planning. Write a PostgreSQL query that returns employees earning one of the five highest distinct salaries among active employees.

Requirements

  1. Use a window function to rank distinct salary levels from highest to lowest.
  2. Return every active employee whose salary is in the top five salary bands, including ties.
  3. Include the employee name, department name, salary, and salary rank. Preserve employees whose department is missing or unmatched.
  4. Exclude inactive employees and employees with a NULL salary. Order the result by salary descending and employee name ascending.
