Magento catalog_product_website is used to store relations between a product and its associated websites.
If your Magento runs with multiple websites and the product is assigned to multiple websites, its relation with the website is stored in the catalog_product_website table.
Table catalog_product_website has two columns.
- product_id — Foreign key with catalog_product_entity
- website_id — Foreign key with store_website
If the Product item is associated with 2 websites, Let’s consider product ID is 10 and website IDs are 1 and 2, There will be two different entries available in the catalog_product_website table to keep the relation between multiple websites for a product.
You can directly check the database table and find a product ID to check how many websites are associated with the given item.
