Laravel 8 Eloquent migration generated error " 1068 Multiple primary key defined" - eloquent

Question

I have the following migration file:
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateHeadersTable extends Migration
{
public function up()
{
Schema::create('headers', function (Blueprint $table) {
$table->increments('entry')->unsigned();
$table->string('id',16);
$table->string('address',256);
$table->string('desciption',512)->nullable()->default('NULL');
$table->tinyInteger('currency',)->default('0');
$table->decimal('sum',13,4);
$table->datetime('entered');
$table->tinyInteger('aborted',)->default('0');
$table->primary('entry');
});
}
public function down()
{
Schema::dropIfExists('headers');
}
}
This file was automatically generated by an online tool from a SQL file. However, when I ran "php artisan migrate," I got the following error:
SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'headers'
already exists (SQL: create table `headers` (`entry` int unsigned not null
auto_increment primary key, `id` varchar(16) not null, `address`

`entered` datetime not null, `aborted` tinyint not null default '0')

I am not familiar with Laravel migration files. How can I fix this? Many thanks!

Answer 1

Do not drop the table manually. use php artisan migrate:rollback
and then re-try php artisan migrate

Answer 2

Error you got states that Table 'headers' already exists in database if you have deleted table from database just check their may be entry in migrations table in database just delete it and run migration again
