MYSQL order by both Ascending and Descending sorting

Question

I have a mysql table with products.

The products have a category ID and a name.

What I\'d like to do is order by category id first descending order and then

Answer 1

You can do that in this way:

ORDER BY `products`.`product_category_id` DESC ,`naam` ASC

Have a look at ORDER BY Optimization

Answer 2

I don't understand what the meaning of ordering with the same column ASC and DESC in the same ORDER BY, but this how you can do it: naam DESC, naam ASC like so:

ORDER BY `product_category_id` DESC,`naam` DESC, `naam` ASC
