选择一行中具有最大值的行，另一列中具有最小值的行

Question

I want to SELECT the row with max value in NumofTrips also with min value in NumofVehicle.

Answer 1

If I were you I would make my SELECT query FROM whatever table and then ORDER BY NumofTrips, then ORDER BY NumofVehicle. You may need to reverse them as you see fit to get them in the right order.

On a completely different note. When it comes to naming, your table fields should be named numOfTrips and numOfVehicle, or simply numTrips and numVehicle, following camelCase naming conventions.

Answer 2

Get single row return from each query

SELECT max(NumOfTrips) FROM table_name

SELECT min(NumOfVehicles) FROM table_name

Answer 3

Just figured out what I need!!!

SELECT id, Base, Basename, NumofTrips / NumofVehicle AS pickup FROM FHV ORDER BY pickup DESC LIMIT 0 , 30
