Code writing examples

GPT-3 is able to write code as well as text.

Here's an example of code-davinci-002 writing a SQL query:

SQL tables (and columns):
* Customers(customer_id, signup_date)
* Streaming(customer_id, video_id, watch_date, watch_minutes)

A well-written SQL query that lists customers who signed up during March 2020 and watched more than 50 hours of video in their first 30 days:
```

Output:

SELECT c.customer_id
FROM Customers c
JOIN Streaming s
ON c.customer_id = s.customer_id
WHERE c.signup_date BETWEEN '2020-03-01' AND '2020-03-31'
AND s.watch_date BETWEEN c.signup_date AND DATE_ADD(c.signup_date, INTERVAL 30 DAY)
GROUP BY c.customer_id
HAVING SUM(s.watch_minutes) > 50 * 60

Helpfully, code-davinci-002 is able to make inferences from variable names; for example, it infers that watch_minutes has units of minutes and therefore needs to be converted by a factor of 60 before being compared with 50 hours.
