Question Topic Difficulty

Over-Budget Projects

SQL

Medium

Over budget on a project is defined when the salaries, prorated to the day, exceed the budget of the project.

For example, if Alice and Bob both combined income make 200K and work on a project of a budget of 50K that takes half a year, then the project is over budget given 0.5 * 200K = 100K > 50K.

Write a query to forecast the budget for all projects and return a label of "overbudget" if it is over budget and "within budget" otherwise.

Note: Assume that employees only work on one project at a time.

Example:

Input:

employees table

Column	Type
`id`	INTEGER
`first_name`	VARCHAR
`last_name`	VARCHAR
`salary`	INTEGER
`department_id`	INTEGER

projects table

employee_projects table
