It is difficult to give a precise answer without specific SQL queries, but generally, when working with tables of departments and employees, you can expect the following results:
- If the query performs a JOIN between tables, the result will be a combined table where each employee's information is associated with their department.
- If the queries use aggregate functions (e.g., COUNT, AVG) with grouping by departments, you can obtain statistics such as the number of employees in each department or the average salary.
For example:
SELECT d.name AS department, COUNT(e.id) AS employee_count
FROM departments d
LEFT JOIN employees e ON d.id = e.department_id
GROUP BY d.name;
This query will return a list of departments with the number of employees in each.
