MySQL通過臨時表循環

Question

我正在嘗試將查詢結果設置為變量，然后在另一個查詢中使用該結果。

所以現在我在成分表中有幾種類型的威士忌酒，我可以找到所有它們，並且具有：

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

這給了我所有我需要的身份證。 然后我嘗試通過以下方式獲取相關數據：

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每個ID運行此查詢

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

或者你也可以嘗試

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
