Sample Solution:
-- Selecting 'first_name', 'last_name', and 'hire_date' columns
SELECT first_name, last_name, hire_date
-- Specifying the table to retrieve data from ('employees')
FROM employees
-- Filtering the results to include only records where 'job_id' is either 'SA_REP' or 'SA_MAN'
WHERE job_id IN ('SA_REP', 'SA_MAN');
Sample Output:
