Why to use DB::raw inside DB::select in Laravel?

Question

Is it mandatory to use the function DB::raw when you are running a query and you are not using the fluent query builder in Laravel?

eg

$result = DB::select("SELECT * FROM users");

$result2 = DB::select(DB::raw("SELECT * FROM users"));

I get the same result in both cases. So why is it necessary to use DB::raw ?

Answer 1

DB::raw() is used to make arbitrary SQL commands which aren't parsed any further by the query builder. They therefore can create a vector for attack via SQL injection.
