Sample Solution:
-- Selecting 'first_name', 'last_name', and 'salary' columns from the 'employees' table
SELECT first_name, last_name, salary
-- Specifying the table to retrieve data from ('employees')
FROM employees
-- Filtering the results based on the condition that 'first_name' ends with the letter 'm' (case-insensitive)
WHERE first_name LIKE '%m';
Sample Output:
first_name | last_name | salary ------------+-----------+--------- Adam | Fripp | 8200.00 Payam | Kaufling | 7900.00 William | Smith | 7400.00 William | Gietz | 8300.00 (4 rows)
