How to seed Country/State data into the Database? Click Here Here, we are going to merge the Country table to the State table using left join

The LEFT JOIN keyword returns all records from the left table (table1), and the matched records from the right table (table2). The result is NULL from the right side if there is no match.

Step 1. Create a new Project in Laravel, so open git bash. Write down the following command:-

Step 2. Create the authentication scaffolding and Country model. Write down the following command:-

$ php artisan make:auth

$ php artisan make:model Country -m

Step 3. Create the State model. Write down the following command:-

$ php artisan make:model State -m

Step 4. Generate a migration file into the database/migrations folder of the Country table.

public function up()
{
        Schema::create('countries', function (Blueprint $table) {
            $table->bigIncrements('country_id');
            $table->string('country_name');
            $table->string('sort');
            $table->integer('phoneCode'); 
            $table->timestamps();
        });
    }Code language: PHP (php)

Step 5. Generate a migration file into the database/migrations folder of State table.

public function up()
{
        Schema::create('states', function (Blueprint $table) {
            $table->bigIncrements('state_id');
            $table->string('state_name');
            $table->integer('country_id');
            $table->timestamps();
        });
    }Code language: PHP (php)

Step 6. Migrate these tables into the MySQL database, so write the following command.

$ php artisan make:controller StateController --resource
