我想查找特定学生和学科的最新月份和年份
请帮我得到上面的结果
最佳答案
试试这个(已编辑):
select t1.Name, t1.Subject, max(month) as Latest_Month_Attended, t2.year as Latest_Year_Attended
from tab t1
join (
select Name, Subject, max(year) as year
from tab
group by Name, Subject
) t2 on t1.name = t2.name and t1.subject = t2.subject and t1.year = t2.year
group by t1.Name, t1.Subject, t2.year
