biginteger in laravel migration code example
Example 1: laravel rollback last migration
php artisan migrate:rollback --step=1
Example 2: laravel create migration
php artisan make:migration add_votes_to_users_table --table=users
php artisan make:migration create_users_table --create=users
Example 3: laravel migration table bigint
$this->bigIncrements('id');
This takes care of making it unsigned, auto increment and primary key
