    To find the difference between the total number of CITY entries and the number of distinct CITY entries, you can use the following SQL query:

    SELECT COUNT(CITY) - COUNT(DISTINCT CITY) AS Difference FROM STATION; This query calculates the total number of CITY entries and subtracts the number of distinct CITY entries, returning the difference. It's useful for identifying duplicate city records in your dataset.
