How to sort NULL values last using Eloquent in Laravel

Question

I\'ve got a many to many relationship between my employees and groups table. I\'ve created the pivot table, and all is working correctly with that. However, I\'ve got a sort

Answer 1

Just add a minus sign to field and change order to DESC.

$q->orderBy(\DB::raw('-`sortOrder`'), 'desc');

Answer 2

I ran into this problem recently using Laravel 5.6, where junkystu answer was perfect for me. However our testing framework uses sqlite, so tests were constantly returning a 500 error.

This is what we came up with, which should be slightly more agnostic of a DB driver.

Ascending

$query->orderBy(DB::raw('column_to_sort IS NULL, column_to_sort'), 'asc');

Descending

$query->orderBy(DB::raw('column_to_sort IS NOT NULL, column_to_sort'), 'desc');
