SQL: How do I select the name of the oldest person in a city for each city? - schema old radio
How do I choose the name of the oldest person in a city by city? Imagine a table with the schema enumeration (name, age, place). I would like to choose the name and age of the oldest person in every city.
I've tried:
SELECT name, MAX (age) of the census City Group
but I'm not sure there is the correct data.

It looks good for me. Make sure that the column of age is a number or an integer, and * not * to varchar. Sorting numbers as strings are funky. Eg 100 comes before 11

The Office does not indicate if this person has little chance of being identified. The board may determine the age of the oldest person in a particular city, but if you say that someone is probably in jail.
