Number filtering
But what if we want to choose a car with small mileage, let it be less than 5000 miles. We need to set the condition to a numeric column.
This also can be done with WHERE statement. For example,
SELECT * FROM audi_cars WHERE mileage < 5000
Comparison operators you also can use for numeric columns:
<- less than<=- less-equal>=- greater-equal ->- greater=- equal<>- not equal.
Now let's try to find the cheapest car in this dataset.
Swipe to start coding
From the audi_cars dataset extract cars with price less than 10 000.
