In Laravel, you can create a table without a primary key by using the Schema builder in a migration file. Here's an example of how you can create a table without a primary key in Laravel:

  1. Create a new migration file by running the following Artisan command:
1
php artisan make:migration create_table_name_without_primary_key --create=table_name_without_primary_key


This command will create a new migration file in the database/migrations directory.

  1. Open the newly created migration file and use the Schema builder to define the table structure without a primary key. Here's an example:

<?php

use IlluminateDatabaseMigrationsMigration;
use IlluminateDatabaseSchemaBlueprint;
use IlluminateSupportFacadesSchema;

class CreateTableWithoutPrimaryKey extends Migration
{
    public function up()
    {
        Schema::create('table_name_without_primary_key', function (Blueprint $table) {
            $table->increments('id'); // Auto-incrementing primary key
            $table->string('name');
            $table->timestamps();
    
            // Remove primary key constraint
            $table->dropPrimary('id');
        });
    }

    public function down()
    {
        Schema::dropIfExists('table_name_without_primary_key');
    }
}


In the migration file, we first define the table structure with an auto-incrementing primary key. Then, we use the dropPrimary method to remove the primary key constraint from the id column.

  1. Run the migration to create the table without a primary key by executing the following Artisan command:
1
php artisan migrate


After running the migration, you should have a table in your database named table_name_without_primary_key without a primary key.
