SQL Salary Threshold Query

EasySQL · PostgreSQL

Problem

Fortitude Systems uses the Workforce Hub to review employee compensation. Write a PostgreSQL query that identifies employees whose salary is equal to or greater than 10,000.

Requirements

  1. Return the employee ID, first name, last name, salary, and department name.
  2. Include employees even when their department is missing or does not match a department record. Display Unassigned for those employees.
  3. Return results in descending salary order, using first name ascending to break salary ties.
