Use Laravel seed and sql files to populate database

1. Add DB::unprepared() to the run method of DatabaseSeeder.

2. Run php artisan db:seed at the command line.

   class DatabaseSeeder extends Seeder {
   
       public function run()
       {
           Eloquent::unguard();
   
           $this->call('UserTableSeeder');
           $this->command->info('User table seeded!');
   
           $path = 'app/developer_docs/countries.sql';
           DB::unprepared(file_get_contents($path));
           $this->command->info('Country table seeded!');
       }
   }
   

I found a package that creates seed files from database tables and rows. It currently supports Laravel 4, 5, 6, 7, 8 and 9:

In the end, it's basically as easy as this:

php artisan iseed my_table

or for multiple occasions:

php artisan iseed my_table,another_table
