Laravel Eloquent ist an object-relational-mapper, an ORM, that makes working with databases a joy. Using it you can try all the SQL queries. DB Facade is a query builder tool used in Laravel. It is similar to doing this: Copy user new User() // only in memory. To make use of the DB facade you need to use the class: use Illuminate\Support\Facades\DB or just use DB.

PDO does not support binding column names. In this guide, you learned how to update database records with Laravel Eloquent. There is no need to clean or sanitize strings passed to the query builder as query bindings. The Laravel query builder uses PDO parameter binding to protect your application against SQL injection attacks. It can be used to perform most database operations in your application and works perfectly with all of Laravel's supported database systems. Laravel's database query builder provides a convenient, fluent interface to creating and running database queries.
