默认数据库表建立方法：
CREATE VIEW `inventory_stock_1` AS SELECT DISTINCT `legacy_stock_status`.`product_id` AS `product_id` , `legacy_stock_status`.`website_id` AS `website_id` , `legacy_stock_status`.`stock_id` AS `stock_id` , `legacy_stock_status`.`qty` AS `quantity` , `legacy_stock_status`.`stock_status` AS `is_salable` , `product`.`sku` AS `sku`FROM (`cataloginventory_stock_status` `legacy_stock_status`JOIN `catalog_product_entity` `product` ON ( `legacy_stock_status`.`product_id` = `product`.`entity_id` ))
