Solution
It seems like you're asking for a SQL query. Here's how you can do it:
SELECT DISTINCT CITY
FROM STATION
WHERE MOD(ID, 2) = 0
ORDER BY CITY;
Here's the step by step explanation:
-
SELECT DISTINCT CITY: This part of the query will select all unique city names from the table. TheDISTINCTkeyword ensures that there are no duplicate city names in the result. -
FROM STATION: This part of the query specifies the table we are selecting data from, which is theSTATIONtable in this case. -
WHERE MOD(ID, 2) = 0: This is the condition for the query. TheMOD(ID, 2)function returns the remainder of the ID divided by 2. If the remainder is 0, that means the ID is even. So this condition will only select rows where the ID is even. -
ORDER BY CITY: This part of the query sorts the result in ascending order by city names. If you want the result in descending order, you can useORDER BY CITY DESCinstead.
