試圖找到最小值

Question

我試圖顯示從AnnualBudget最小值，這裏是到目前爲止，我已經做了代碼：

SELECT WARD.HospitalCode, 
     HOSPITAL.HospitalCode Name, 
     WardNo, 
     AnnualBudget 
FROM WARD, 
    HOSPITAL 
WHERE (AnnualBudget) = 
    (SELECT AnnualBudget 
    FROM WARD 
    WHERE AnnualBudget = 
     (SELECT MIN(AnnualBudget) 
      FROM WARD 
      WHERE AnnualBudget > 
       (SELECT MIN(AnnualBudget) 
       FROM WARD 
     ) 
    ) 
); 

但而不是選擇最小值，它實際上選擇最大價值，任何人都可以幫忙嗎？

Answer 1

下面的查詢會給你的東西比分鐘時

select min(annualbudget) 
from ward 
where annualbudget > (
    select min(annualbudget) 
    from ward 
) 

如果你想分鐘，試試這個：我不太預言這些天，但它應該工作）

select (stuff) 

from ward w 
join hospital h on h.hospitalId = w.hostpitalId 

where w.annualbudget = (select min(annualbudget) from ward) 

Answer 2

不應該這樣更像嗎？

SELECT W.HospitalCode, H.HospitalCode, Name, WardNo, AnnualBudget 
FROM WARD W, HOSPITAL H 
WHERE W.HospitalCode = H.HospitalCode 
    and W.AnnualBudget = (Select MIN(AnnualBudget) FROM WARD W2 
               WHERE W2.HospitalCode = W.HospitalCode) 

我假設WARD中的醫院代碼是一個外鍵，並且您希望每個醫院的預算最低，對吧？
