Aliasing Columns

Problem

The new frontend application requires API data to match exact JSON keys. Retrieve the first_name and last_name of all employees, but rename the columns in the output to First and Last.

Database Schema

Table: employees

  • employee_id (INT): Unique identifier for the employee.
  • first_name (VARCHAR): First name of the employee.
  • last_name (VARCHAR): Last name of the employee.
  • salary (INT): Employee's salary.
  • department_id (INT): Foreign key referencing the department.
  • manager_id (INT): Foreign key referencing the manager (another employee).
  • hire_date (DATE): Date the employee was hired.

Table: departments

  • department_id (INT): Unique identifier for the department.
  • department_name (VARCHAR): Name of the department.
