多站点的时候，有部分视图未使用默认值，如在后台全手工修改工作量较大，目前仅需要执行以下SQL，删除所有额外视图的内容
DELETE FROM `catalog_product_entity_text` where store_id = 1; DELETE FROM `catalog_product_entity_datetime` where store_id = 1; DELETE FROM `catalog_product_entity_decimal` where store_id = 1; DELETE FROM `catalog_product_entity_int` where store_id = 1; DELETE FROM `catalog_product_entity_varchar` where store_id = 1;
