To achieve that, create a new PHP file in your Magento directory which is the same level as app, lib, pub ... with the following content:

ini_set('display_errors', 1);
ini_set('memory_limit', '5G');

use Magento\Catalog\Model\Product\Type;
use Magento\Catalog\Model\ResourceModel\Product\Collection;
use Magento\Framework\App\Bootstrap;

require __DIR__ . '/app/bootstrap.php';

$bootstrap = Bootstrap::create(BP, $_SERVER);

$objectManager = $bootstrap->getObjectManager();
$state = $objectManager->get('Magento\Framework\App\State');

$collectionFactory = $objectManager->create(Magento\Catalog\Model\ResourceModel\Product\CollectionFactory::class);
/** @var Collection $collection */
$collection = $collectionFactory->create();
$collection->addAttributeToFilter('type_id', ['eq' => Type::TYPE_SIMPLE])->load();

foreach ($collection as $product) {
    $product->setData('category_ids', null)->save();

For example, you set the file name removeAllCategoriesFromSimpleProducts.php, to execute the script, you should run the following command from the SSH terminal:

php removeAllCategoriesFromSimpleProducts.php

  • PHP Fatal error: Uncaught PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'tommy-hilfiger-sunglasses-th-1556-s-08a-ir-black-gray-1' for key 'URL_REWRITE_REQUEST_PATH_STORE_ID' in /var/www/vhosts/stagingdiscountedsunglasses/htdocs/vendor/magento/framework/DB/Statement/Pdo/Mysql.php:91 Stack trace: Feb 2, 2023 at 6:56
  • That means your URL Rewrites data (for products) has problem(s). To fix this issue, from admin, go to Marketing > URL Rewrites, and filter by the Request Path with the key in the error, you will see some duplicate records and you should resolve it. Or if you see many products have URL Rewrites duplicates, you should use an extension to resolve the issue: github.com/elgentos/magento2-regenerate-catalog-urls

  • i am having issue with suppose this url key " bvlgari-eyeglasses-bv4165-504-dark-havana-women-1" but i see only one entry in url rewrites prnt.sc/TKUNFF1veAIL . So there is no duplicate entry here Feb 2, 2023 at 8:21
  • There are some issues with your URL Rewrites, please use the extension I mentioned above to re-generate URL Rewrites then run my code. I've tested my code before sharing the code (with Magento default with sample data and the site is multiple stores), so it should work as expected.
