Magento bulk price changes

Question

What I\'m trying to do is, a bulk price change on products in a certain category. We receive suggested retail prices from our vendor, but sometimes these don\'t work for us. So

Answer 1

Honestly, B00MER has the right idea, but I've also had to do similar things in a pinch before. Plus, I felt like writing a little SQL. If you just want to multiply costs by 1.2 for all products in a category, you can do something like this:

update catalog_product_entity_decimal
  set value = value*1.2
  where attribute_id = 75 and
        entity_id IN (select product_id from catalog_category_product
                    where category_id = X);

You'll doubtless need to reindex everything and check your results to make sure. Obviously, replace X with your target category, and it appears that you use a table prefix of m_, so append that too (I'm leaving it off for other searchers who come here).

Hope that helps!
