Mysql，联接查询，混淆

Question

我面临的问题是，我想连接这两个查询。

   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;

此查询不能按预期工作，当有多个结果时，它会返回1个结果，并且trate是所有结果的总和，而不仅仅是特定RecipeID的结果

Answer 1

我想这就是你要找的：

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;
