Answer:
Explanation:
D. This should produce a correct output.
I’m making a number of assumptions here. More specifically, that this is likely referring to the standard MySQL syntax (or identical in this context) and that both tables “employees” and “departments” contain columns “employee_id”, “hire_date”, and “department_name”. If one or both of these assumptions are wrong, then the answer should be A (error).
SELECT employee_id, hire_date, department_name
FROM employees, departments
WHERE departments.department_id = employees.department_id
This WHERE line compares the department_id from the “departments” table and “employees” table. It will only SELECT the “employee_id”, “hire_date” and “department_name” of the records FROM both tables IF their “department_id” values are the same.
