How to use paginate() with a having() clause when column does not exist in table

Question

I have a tricky case ...

Following database query does not work:

DB::table(\'posts\')
->select(\'posts.*\', DB::raw($haversineSQL . \' as distance         


        

Answer 1

You can calculate the distance in the WHERE part:

DB::table('posts')
    ->whereRaw($haversineSQL . '<= ?', [$distance])
    ->paginate(10);

If you need the distance value in your application, you'll have to calculate it twice:

DB::table('posts')
    ->select('posts.*', DB::raw($haversineSQL . ' as distance'))
    ->whereRaw($haversineSQL . '<= ?', [$distance])
    ->paginate(10);
