  • You don't need to write this field in where clause if you want to remove it from the collection. Magento2 has already used this and you can check in these files for your reference : 1) vendor/magento/module-ui/DataProvider/AbstractDataProvider.php, 2) vendor/magento/module-catalog/Model/ResourceModel/Product/Collection.php Apr 23, 2020 at 5:55
