SELECT * FROM CITY WHERE POPULATION>100000 AND CountryCode = 'USA';

Anyone knows why I can't submit my code? Clicking the button gets me no where

with t as (select * from city where countrycode = "USA") select * from t where population>100000;

select * from city where population > 100000 having CountryCode='USA';

slect * from city where country code ="usa" and population > 100000;
