Question

我有一个编写查询的任务，使用northwind 2007数据库获取烘焙食品和干果和坚果中所有产品的产品名称，库存数量，类别和单价。我的查询如下：

SELECT PRODUCT_NAME, QUANTITY_PER_UNIT, CATEGORY, LIST_PRICE
FROM PRODUCTS
WHERE CATEGORY = [Dried Fruits & Nuts] OR [Baked Goods & Mixes];

有人能帮我这个吗？

Answer 1

大概：

SELECT 
    PRODUCT_NAME, QUANTITY_PER_UNIT, CATEGORY, LIST_PRICE
FROM 
    PRODUCTS
INNER JOIN 
    CATEGORIES ON PRODUCTS.CATEGORYID = CATEGORIES.CATEGORYID
WHERE 
    CATEGORIES.DESCRIPTION = "Dried Fruits & Nuts" 
    OR 
    CATEGORIES.CATEGORY = "Baked Goods & Mixes";

Microsoft Access中的SQL查询
