SQL查詢沒有顯示正確的數據

Question

我有這個表：

Recipe = (idR, recipeTitle, prepText, cuisineType, mealType) 
Ingredient = (idI, ingrDesc) 
RecipIngr = (idR*, idI*) 

，我試圖顯示IDR和包含的成分蜂蜜或芥末配方標題。這是我的查詢

select idr, recipetitle 
from recipe 
where idr IN (select idr from recpingr where idi = 
(select distinct idr from ingredient where ingrdesc like '%honey%')) 
INTERSECT 
select idr, recipetitle 
from recipe 
where idr IN (select idr from recpingr where idi = 
(select distinct idr from ingredient where ingrdesc like '%mustard%')) 
ORDER BY idr; 

由於某種原因，這將不會顯示正確的數據，我不知道我做錯了什麼。任何幫助？我的查詢有問題嗎？

Answer 1

像這樣的幫助？

SELECT r.idr, r.recipetitle 
FROM recipe r 
INNER JOIN recipingr ring 
    ON ring.idr = r.idr 
INNER JOIN ingredient ing 
    ON ing.idi = ring.idi 
WHERE ing.ingrdesc LIKE '%honey%' 
OR ingrdesc LIKE '%mustard%' 
ORDER BY r.idr 

Answer 2

我想你過度工程它。爲什麼不能是這樣的：

select idr, recipetitle 
from recipe r join recipInbg ri on r.idr = ir.idr 
join ingredient i on ri.idI = i.idI 
where ingrdesc like '%honey%' 
or ingrdesc like '%mustard%' 

Answer 3

在這裏你去：

select r.idr, r.recipeTitle from recipe r, ingredient i, recipIngr ri 
    where r.idR=ri.idR and ri.idI=i.idI and 
    (i.ingrDesc like '%honey%' or i.ingrDesc like '%mustard%')
