select count('vehicules.id')
from vehicules
INNER JOIN (equipements, contenirs)
ON (contenirs.vehicule_id = vehicules.id AND contenirs.equipement_id = equipements.id)
WHERE(vehicules.KMActuel-contenirs.dernierKM > equipements.kilometrageMax);
This is the code I want to execute in Laravel. I tried the following code:
$special = DB::select("SELECT COUNT('vehicules.id') FROM vehicules INNER JOIN (equipements, contenirs) ON (contenirs.vehicule_id = vehicules.id AND contenirs.equipement_id = equipements.id) WHERE(vehicules.KMActuel-contenirs.dernierKM > equipements.kilometrageMax)");
I called a variable in the view and got the following error:
htmlspecialchars() expects parameter 1 to be string, array given (View: C:\laragon\www\GSMV\resources\views\dash.blade.php)

You cannot execute expressions in strings passed to regular Eloquent methods. You must use a primitive expression that can be parsed accordingly:
DB::table('vehicules') ->join('contenirs', 'vehicules.id', 'contenirs.vehicule_id') ->join('equipements','equipements.id','contenirs.equipement_id') ->whereRaw('vehicules.KMActuel-contenirs.dernierKM > equipements.kilometrageMax') ->select('vehicules.*', 'contenirs.designation') ->count('vehicules.id');
