Question

我有以下MS-Access SQL表： -

NAME，SUBJECT，SCORE

..我需要找到平均分数，最高分和最高分数的主题。我设法生成以下查询但不确定如何合并SUBJECT字段： -

SELECT  NAME,  Avg(SCORE) AS AverageScore, MAX(SCORE) AS best_score
FROM Scoretable
GROUP BY NAME

有什么想法吗？

Answer 1

select sm.NAME, sm.AverageScore, sm.best_score, s.SUBJECT
from (
    SELECT  NAME,  Avg(SCORE) AS AverageScore, MAX(SCORE) AS best_score 
    FROM Scoretable 
    GROUP BY NAME 
) sm
inner join Scoretable s on sm.NAME = s.NAME 
    and sm.best_score  = s.SCORE

如何向SQL Group By子句添加其他字段
