Mysql，加入查询，一头雾水

Question

我面临的问题是，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;

这个查询没有按预期工作，当有多个结果时它会带来 1 个结果，并且比率是所有结果的总和，而不仅仅是那个特定的 RecipeID

我想这就是您要找的:

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;
