Mysql，加入查询，困惑

Question

我面对的问题是，我想加入这两个查询。

SELECT recipes.RecipeID ,recipes.Name,recipes.ImageThumb,recipes.RatingTotal, 
    count(ratings.RecipeID) AS trates 
    FROM recipes 
     JOIN ratings 
      ON ratings.RecipeID = recipes.RecipeID 
    WHERE recipes.Name LIKE '%ade%' 
    ORDER BY Name; 

根据需要此查询不工作，它带来1分的结果时，有一个以上，且trates之际，总的所有结果，而不是只对特定的RecipeID

我的认为这是你正在寻找的：

SELECT recipes.RecipeID ,recipes.Name,recipes.ImageThumb,recipes.RatingTotal, 
     COUNT(ratings.RecipeID) AS trates 
FROM recipes 
    LEFT JOIN ratings 
     ON ratings.RecipeID = recipes.RecipeID 
WHERE recipes.Name LIKE '%ade%' 
GROUP BY RecipeID 
ORDER BY Name;
