Magento 2 - 以编程方式删除产品的 Tierprices

Question

I tried several ways to remove tierprices and looked they were performed well with no issues. But there are no changes in products and the tierprices are still remain. Please recommend any solution for this please.

Answer 1

$connection = $this->resource->
  getConnection(\Magento\Framework\App\ResourceConnection::DEFAULT_CONNECTION);

$sql = 'DELETE FROM `catalog_product_entity_tier_price` 
       WHERE `value_id` = ' . $price['price_id'];

$connection->query($sql);

We can remove tierprices directly via database by running query.
