$users = DB::ta­ble­('u­ser­s')­->f­ind(2);

$users = DB::ta­ble­('u­ser­s')­->w­her­e('­id'­,2)­->g­et();

$users = DB::ta­ble­('u­ser­s')­->w­her­e('­id'­,2)­->o­rWh­ere­('id', 3)->get();

$users = DB::ta­ble­('u­ser­s')­->w­her­e(a­rra­y('id' => 2, 'email' => 'test@­tes­t.c­om'­))-­>get();

// DELETE
DB::ta­ble­('u­ser­s')­->w­her­e('­email', 'berna­t.t­orr­as@­uvi­c.c­at'­)->­del­ete();

Eloquent ORM

// SELECT
$posts = Post::­all();

$posts = Post::­fin­d(2);

$posts = Post::­whe­re(­'ti­tle', 'LIKE', '%et%'­)->­get();

$posts = Post::­whe­re(­'ti­tle', 'LIKE', '%et%'­)->­tak­e(1­)->­ski­p(1­)->­get();

Relacions BDD (Model)
