How to load new product collection in Magento 2 something like
$collection->addAttributeToFilter('parent_id', null);
I want all simple product which is not associate with configurable which mean it has no parent.
Or any other approach ?
I have added following join to the product collection query
$collection->getSelect()->joinLeft(
'catalog_product_super_link',
'e.entity_id = catalog_product_super_link.product_id'
)->where ("catalog_product_super_link.product_id IS NULL");
and got the desired collection.
