SQL Query for Third Largest

MediumSQL · PostgreSQL

Problem

Sun Life Financial's QA team needs to validate salary-ranking logic in an employee reporting query. Write a PostgreSQL query that identifies employees earning the third-highest distinct salary among active employees with recorded compensation.

Requirements

  1. Join employees to employee_compensation using employee_id.
  2. Exclude inactive employees and rows where salary is NULL.
  3. Rank distinct salary values from highest to lowest and return every employee tied at rank 3.
  4. Order the results by salary descending and employee ID ascending.
