DB::insert('insert into users (id, name, email, password) values (?, ?, ? , ? )',[1, 'Laravel','laravel@test.com','123']);

$user = DB::select('select * from users where id = ?', [1]);
//我们还 可以看到在执行查询的时候使用了参数绑定，以避免SQL注入。除此之//外还可以使用命名绑定：
$user = DB::select('select * from users where id = :id', [':id'=>1]); 

$affected = DB::update('update users set name="LaravelAcademy" where name = ?', ['Academy']);

$deleted = DB::delete('delete from users');
