Is it possible to see raw sql query?

DB::enableQueryLog();

Bill::with(['user', 'project'])->get();

DB::getQueryLog();

But the best is to use debugbar

https://github.com/barryvdh/laravel-debugbar

use Illuminate\Support\Facades\DB;

DB::enableQuery();
Bill::with(['user', 'project'])->get();
dd(DB::getQueryLog()); // list of all the queries

Or just do

Bill::with(['user', 'project'])->toSQL();

or

Bill::with(['user', 'project'])->dd();

or

Bill::with(['user', 'project'])->dump();

But I agree with @michaloravec that the debugbar is the best option if you don't have the Tinkerwell app.
