Answer 1

您正在寻找ORDER BY而不是GROUP BY

Answer 2

You need order by instead of group by

select * from table order by city

There might be another issue when you have city names mixed with lower and upper case and it will not order properly in that case so you need to format the order by as

select upper(city) from test
order by lower(city);

or

select city from test
order by lower(city);

Answer 3

order by will helps you

select * from tablename order by city

---

Try with length of the string

select * from cityname order by CHAR_LENGTH(city) desc

Working Fiddle

Answer 4

Try ORDER BY as other answers suggest (the one from Abhik seems very complete)

Aside from that If you want to know how many cities of each type do you have you can do something like this:

SELECT city, COUNT(city) FROM table GROUP BY city ORDER BY city

This query will return

LA | 3

New York | 2

This will give you a better way to count your cities (if you want to do something like this)
