2Bob20
3Charlie30

Departments

department_iddepartment_name
10Sales
20Marketing
30IT

Example: INNER JOIN to get employee names with their department names

SELECT e.name, d.department_nameFROM Employees eINNER JOIN Departments d ON e.department_id = d.department_id;

Result:

namedepartment_name
AliceSales

  • Only rows with matching department_id in both tables are included.
