mysql - Mysql遍历临时表

Question

我正在尝试将查询结果设置为变量，然后在另一个查询中使用该结果。

所以现在我的配料表中有几种威士忌，我可以找到所有这些威士忌，并且：

CREATE TEMPORARY TABLE TempTable (Ingredient_Id int); 
Insert into TempTable Select Ingredient_Id from ingredients where INSTR(Ingredient_Name,'Whiskey')>0;

这给了我所有我需要的身份证。然后我试图通过以下方式获取相关数据：

select drink_names.*,ingredients.*, drink_recipes.*
from drink_recipes
Left JOIN drink_names ON drink_recipes.Drink_Id = drink_names.Drink_Id
Left JOIN ingredients ON ingredients.Ingredient_Id = drink_recipes.Ingredient_Id
where drink_recipes.Ingredient_Id in TempTable #This is the problem
Order By Drink_Name

我不知道如何使用TempTable

Answer 1

select drink_names.*,ingredients.*, drink_recipes.*
from drink_recipes
Left JOIN drink_names ON drink_recipes.Drink_Id = drink_names.Drink_Id
Left JOIN ingredients ON ingredients.Ingredient_Id = drink_recipes.Ingredient_Id
where drink_recipes.Ingredient_Id in 
(
  Select Ingredient_Id 
  from ingredients 
  where INSTR(Ingredient_Name,'Whiskey')>0
)
Order By Drink_Name

或者你也可以试试

select drink_names.*,ingredients.*, drink_recipes.*
from drink_recipes
Left JOIN drink_names ON drink_recipes.Drink_Id = drink_names.Drink_Id
Left JOIN ingredients ON ingredients.Ingredient_Id = drink_recipes.Ingredient_Id
                      AND INSTR(ingredients.Ingredient_Name,'Whiskey') > 0
Order By Drink_Name
