在GROUP内部进行PHP / MySQL排序

Question

I have a case where I have to group results from table by brands and then order by some other column.

I get my brands from an array. The problem is that when I group by brand this group is sorted by ID (inside group). Is there a way to sort (order by) inside group?

Here is my array and mysql query.

$laptop_brands = array("Acer", "Apple", "Dell", "HP-Compaq", "IBM-Lenovo", "Sony", "Toshiba", "ASUS", "Fujitsu", "Gateway");

$get_videos_query = "SELECT * FROM users_video WHERE location = 'location_1' AND brand IN ('" . implode("','", $laptop_brands) . '\') GROUP BY brand ORDER BY FIELD (brand, "Acer", "Apple", "Dell", "HP-Compaq", "IBM-Lenovo", "Sony", "Toshiba", "ASUS", "Fujitsu", "Gateway"), official DESC';

Answer 1

SELECT * FROM (SELECT * FROM users_video WHERE location = 'location_1' AND brand IN ('" . implode("','", > $laptop_brands) . '\') GROUP BY brand ) AS P ORDER BY FIELD (brand, "Acer", "Apple", "Dell", "HP-Compaq", "IBM-Lenovo", "Sony", >"Toshiba", "ASUS", "Fujitsu", "Gateway"), official DESC

you can select from your result then order them
