I found recently that adding a new store view to Magento was a pretty straightforward task, however I needed all products on the new store view to be the same as another. All new store-view catalog data inherits from the default store scope instead of a sibling store-view’s data. Copying this content from one store view to another through the Magento admin area is a very cumbersome task, especially if you have a large catalog of products with store-view specific data. I also didn’t think it was worth running code through a controller, so I decided to dust off my old SQL boots and take the fight to the database. This could easily be modified to take a product_id parameter as well, so get your teeth in.

Ultimately this wasn’t overly difficult, and it’s probably a useful exercise for someone trying to learn EAV. Since EAV bloats out tables quite significantly, there’s a number of tables to consider. I think I’ve covered them all; at least I have for my purposes. Let me know if there’s something you encounter that isn’t covered here and I’ll be sure to add it.

Also, as usual, always try this on a development server with a separate database.

All you have to do is change the ID’s defined at the start.
