Sql 如何在access中为我的情况查询多个数据库

这是我的条件

我有三个表，其中有以下列

Recipe 
   - rID
   - pID
   - ingID
   - ingAmount

Product
   -pID
   -pName

Ingredient
   - ingID
   - ingName

对于Recpe表，Recipe.ingID、Recipe.pID引用自产品的Product.pID（主键），而相同的配料.ingID也引用自Product.ingID

总的来说

Recipe.pID = Product.pID
Recipe.ingID = Product.pID
Recipe.ingID = Ingredient.ingID

我想使用ACCESS中的单个查询检索以下列

pID | pName | ingID | ingName | ingAmount |

我尝试了以下几点：

SELECT Recipe.pID, Product.pName, Recipe.ingID, 
       Ingredient.ingName, Recipe.ingAmount 
  FROM Recipe, Product, Ingredient 
 WHERE Recipe.pID = 5 
       AND (
            Recipe.ingID = Ingredient.ingID 
            OR Recipe.ingID = Product.pID
           );

问题是，

（Recipe.ingID=component.ingID或Recipe.ingID=Product.pID）

首先计算零件，因此查询多行

如果您得到了我想要的，请帮助我。

您是否尝试过选择DISTINCT？这就是你想要的吗？条件应该是

Recipe.ingID=component.ingID和Recipe.pID=Product.pID

@Florin:Nope！我希望Recipe.ingID=component.ingID等于true或Recipe.ingID=product.pID等于true@user995387当您说“查询多行”时，问题是什么，您是否获得重复记录，如果是，在哪些字段上？是ingID字段的重复记录您是否尝试选择DISTINCT？这就是你想要的吗？条件应该是

SELECT Recipe.pID, Recipe.ingID, Recipe.ingAmount, 
       Ingredient.ingName AS element_name, 
       'Ingredient' AS element_type
  FROM Recipe INNER JOIN Ingredient
          ON Recipe.ingID = Ingredient.ingID

  FROM Recipe INNER JOIN Product
          ON Recipe.ingID = Product.pID
 WHERE Recipe.pID = 5;
