Show the first_name, last_name, and height of the patient with the greatest height

It seems like you're asking for a SQL query. Here's how you can do it:

SELECT first_name, last_name, MAX(height) 
FROM patients;

This query will return the first name, last name, and maximum height from the 'patients' table. However, please note that if there are multiple patients with the same maximum height, this query will only return one of them. If you want to get all patients with the maximum height, you would need to use a subquery:

SELECT first_name, last_name, height
FROM patients
WHERE height = (SELECT MAX(height) FROM patients);

This query first finds the maximum height in the 'patients' table, and then returns all patients with that height.
