Sorting in DESCending order
But what if we want to get the highest observation? As you remember, sorting in SQL is realized in ascending order, so the biggest values are on the bottom.
In SQL you can easily sort in reverse (descending) order. To do it use DESC keyword followed or preceded by column name. You can also put column names within the parenthesis of DESC keyword. So, there are two variants of using DESC:
DESC(col_name);col_name DESC;
For example, we can order cars by mileage, but this time in descending order.
SELECT * FROM audi_cars ORDER BY mileage DESC
Please note, that there is also
ASCkeyword in SQL used for ascending sorting. Since default sorting in SQL is in ascending order, this keyword is rarely used.
Swipe to start coding
From the audi_cars table extract all the cars sorted by column tax in descending order.
