SELECT `virtuemart_product_price_id` FROM `k2xip_virtuemart_product_prices` WHERE `virtuemart_product_id` = 257 AND `price_quantity_start` = 0 AND `price_quantity_end` = 0 AND `virtuemart_shoppergroup_id` IS NULL AND `product_currency` = 64 AND `product_price_publish_up` IS NULL AND `product_price_publish_down` IS NULL
To modify/delete a price why I need to know the current price?Who says that? I am only saying that CSVI can't find the existing price in your database. I asked you a question you didn't answer. This makes it impossible for me to help you.
