Laravel DB :: Raw无法按预期工作

Question

I am forming the query below:

SELECT *, ACOS( SIN( RADIANS( `latitude` ) ) * SIN( RADIANS('17.4073331') ) + COS( RADIANS( `latitude` ) )* COS( RADIANS('17.4073331')) * COS( RADIANS( `longitude` ) - RADIANS('78.3802307'))) * 6380 AS distance 
FROM bbq_branches_by_city 
HAVING distance <= 20

I am doing like below in laravel:

DB::table('bbq_branches_by_city')
  ->select(DB::raw("*, ACOS( SIN( RADIANS( `latitude` ) ) * SIN( RADIANS($lat) ) + COS( RADIANS( `latitude` ) )* COS( RADIANS($lat)) * COS( RADIANS( `longitude` ) - RADIANS($long))) * 6380 AS distance"))
  ->havingRaw("distance <= 20")
  ->get();

Can you let me know where I am mistaking?

Answer 1

Try this:

DB::table('bbq_branches_by_city')
     -> select(["*",DB::raw("ACOS( SIN( RADIANS( `latitude` ) ) * SIN( RADIANS($lat) ) + COS( RADIANS( `latitude` ) )* COS( RADIANS($lat)) * COS( RADIANS( `longitude` ) - RADIANS($long))) * 6380 AS distance")])
     ->havingRaw("distance<=20")
     ->get();

Just make the select as array like ['*','distance']
