laravel having: Column not found

Question

my following code is like this:

$places = DivePlace::selectRaw(\"*,(st_distance_sphere( POINT(\".$lon.\",\".$lat.\") ,  point(lon, lat))/1000) as distance\")         


        

Answer 1

You need to repeat distance definition because for pagination Laravel uses only count(*) for columns, so it should be:

$places = DivePlace::selectRaw("*,(st_distance_sphere( POINT(".$lon.",".$lat.") ,  point(lon, lat))/1000) as distance")
    ->havingRaw("(st_distance_sphere( POINT(".$lon.",".$lat.") ,  point(lon, lat))/1000) < ".$radius)
    ->orderBy("distance")
    ->paginate(10);

You could also use bindings for the query, so better would be:

$places = DivePlace::selectRaw("*,(st_distance_sphere( POINT(?, ?) ,  point(lon, lat))/1000) as distance",[$lon, $lat])
    ->havingRaw("(st_distance_sphere( POINT(?, ?) ,  point(lon, lat))/1000) < ?", [$lon, $lat, $radius])
    ->orderBy("distance")
    ->paginate(10);

Answer 2

->where(DB::raw("(ST_Distance_Sphere(POINT(".$lon.",".$lat."), POINT(lon,lat))/1000)"), '<', 200)

instead of ->havingRaw("(st_distance_sphere( POINT(?, ?) , point(lon, lat))/1000) < ?", [$lon, $lat, $radius])
