Answer from AI

This SQL query selects names from the PERSON table and corresponding phone numbers from the PHONE table using a LEFT JOIN. This means that all people from PERSON will be shown, even if they do not have a phone number (in which case the NUMBER field will be NULL).

Example result:

NAME NUMBER
alice 123-456-7890
john NULL
bill 987-654-3210

If a person has multiple numbers, there will be a separate row for each number with their name.
