Below is code for get collection data that contain product with new SKU based on created data..
//get data that new SKU product
->addAttributeToFilter('status', array('eq' => Mage_Catalog_Model_Product_Status::STATUS_ENABLED))
->addAttributeToFilter('created_at', array('date' => true, 'from' => $todayDate,'to' => $date));
We can select what attribute that we need to be shown and then if we want to filter based on another attribute, we can use “addAttributeToFilter“.
Hopefully can help you, thanks.
