Departments With High Average Salary

EasySQL15 min10 XP

Problem

Return department and avg_salary for departments with average salary above 70000.

Why This Matters

SQL interviews usually test whether you can turn a business question into the right rows, grouping level, join type, and edge-case behavior.

Schema

employees(employee_id INTEGER, department TEXT, salary INTEGER)

Examples

Example 1
InputEng average is 80000, Ops is 60000
OutputEng only

HAVING filters after department averages are calculated.

Constraints

  • Return only the requested columns.
  • Use deterministic ORDER BY when multiple rows are returned.
  • Assume SQLite-compatible SQL unless the prompt states otherwise.
