Laravel Eloquent Select CASE?

Question

Y at-il quelqu'un avec une expérience en PHP & Laravel Eloquent qui peut m'aider à résoudre cette déclaration? J'essaie d'injecter un CAS ... WHEN .. END ... dans une méthode raw(). Il semblait que c'était complètement ignoré. La documentation existante n'a pas été. J'ai essayé plusieurs choses différentes pour ne pas l'emporter. Je suis en train de retirer ceci:

SELECT shares.id, ..., 
    CASE WHEN users.id = <CurrentUser> THEN 1 ELSE 0 END AS is_user, 
    ... 
FROM <table> 
... 

Le code source est ci-dessous:

$shares = Share::where('shares.status', '=', SHARE_STATUS_APPROVED) 
        ->where('shares.deleted', '=', '0') 
        ->where('locations.lat', '<=', $nelat) 
        ->where('locations.lat', '>=', $swlat) 
        ->where('locations.lng', '>=', $nelng) 
        ->where('locations.lng', '<=', $swlng) 
        ->where('users.id', '=', $user) 
        ->orWhere('shares.connected_user_id', '=', $user) 
        ->join('users', 'shares.user_id', '=', 'users.id') 
        ->join('locations', 'locations.id', '=', 'users.location_id') 
        ->join('provinces', 'provinces.id', '=', 'locations.province_id') 
        ->join('countries', 'countries.id', '=', 'locations.country_id') 
        ->select('shares.id AS share_id', 'users.id AS user_id', 'shares.connected_user_id', 'shares.original_language_id', 'shares.image', 
         'users.first_name', 'users.last_name', 'users.email', 
         'locations.city', 'provinces.name', 'countries.code', 
         'locations.lat', 'locations.lng', 
         'shares.created_at') 
        ->raw('(CASE WHEN users.id = ' . $user . ' THEN 1 ELSE 0 END) AS is_user') 
        ->orderBy('shares.created_at', 'desc') 
        ->orderBy('users.id', 'asc') 
        ->orderBy('shares.connected_user_id', 'asc') 
        ->get(); 

Answer 1

Déplacez votre raw() appel dans l'instruction SELECT:

->select('shares.id AS share_id', 'users.id AS user_id', 'shares.connected_user_id',  
    'shares.original_language_id', 'shares.image', 
    'users.first_name', 'users.last_name', 'users.email', 
    'locations.city', 'provinces.name', 'countries.code', 
    'locations.lat', 'locations.lng', 
    'shares.created_at', 
    DB::raw('(CASE WHEN users.id = ' . $user . ' THEN 1 ELSE 0 END) AS is_user') 
) 
->orderBy('shares.created_at', 'desc')

Answer 2

Vous pouvez également utiliser selectRaw à la place.

->selectRaw("shares.id AS share_id, users.id AS user_id , 
    shares.connected_user_id ,  
     shares.original_language_id, shares.image, 
     users.first_name, users.last_name, users.email, 
     locations.city, provinces.name, countries.code, 
     locations.lat, locations.lng, 
     shares.created_at, 
     (CASE WHEN users.id = {$user} THEN 1 ELSE 0 END) AS is_user)") 
    ->orderBy('shares.created_at', 'desc')
