php - How to use raw sql Pagination in Laravel5?

Question

This is my Controller code:

$sql = "SELECT *,earth_distance(ll_to_earth(team.lat, team.lng), ll_to_earth(23.1215939329,113.3096030895)) AS distance FROM team where earth_box(ll_to_earth(23.1215939329,113.3096030895),1000) @> ll_to_earth(team.lat, team.lng); ";
$result = DB::select( DB::raw( $sql ) );

How can I add pagination to this code to build my restful api?

iOS or android will send the "next page" parameter, how to use it and find the next section data?

Answer 1

As far as I know you can't paginate raw query, here's why:

$result = DB::select($sql); 

$result here will have the array type and paginate() is the method from the IlluminateDatabaseQueryBuilder class.

Your case can be performed this way:

$items = DB::table('team')   
    ->selectRaw('SELECT *,earth_distance(ll_to_earth(team.lat, team.lng), ll_to_earth(23.1215939329,113.3096030895)) AS distance')
    ->whereRaw('earth_box(ll_to_earth(23.1215939329,113.3096030895),1000) @> ll_to_earth(team.lat, team.lng)')
    ->paginate(10);

foreach($items as $item) {
    echo $item->distance;
}

As you can see minimal effort is needed here to separate raw query to selectRaw() and whereRaw() methods.
