How to bind parameters to a raw DB query in Laravel that's used on a model?

Question

Re,

I have the following query:

$property = 
    Property::select(
        DB::raw(\"title, lat, lng, ( 
            3959 * acos( 
                co

I encountered same issue just recently and the answer is in that error message mixed named and positional parameters. In your case, the :lat and :lng are named parameters while you have $radius as positional. So one possible fix to your issue is make use of havingRaw() and apply named parameters.

--havingRaw('distance < :radius', ['radius' => $radius])
