试图找到最小值

Question

我试图显示从AnnualBudget最小值，这里是到目前为止，我已经做了代码：

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 
     ) 
    ) 
); 

但而不是选择最小值，它实际上选择最大价值，任何人都可以帮忙吗？

Answer 1

下面的查询会给你的东西比分钟时

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

如果你想分钟，试试这个：我不太预言这些天，但它应该工作）

select (stuff) 

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

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

Answer 2

不应该这样更像吗？

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) 

我假设WARD中的医院代码是一个外键，并且您希望每个医院的预算最低，对吧？
