select max(Score) as Score,Province from RZ_ExamineePK
group by Province 有这种一句SQL,我想得到每条数据的ID,咋写呢

2 OrId int 4 10 0 ((0))
3 OrUid int 4 10 0 ((0))

------解决方案--------------------
select * from RZ_ExamineePK as t where not exists(select 1 from RZ_ExamineePK where Province=t.Province and Score>t.Score)
------解决方案--------------------
select *
from RZ_ExamineePK a
where exists (select 1 from (select max(Score) as Score,Province from RZ_ExamineePK
group by Province)b where a.score=b.score and a.province=b.province)
------解决方案--------------------
请问版版,你敲sql 语句的时候,后面回车自己敲的,还是用工具自动生成的,换行之后看上去蛮舒服的.
------解决方案--------------------
再关联回来:
select b.id,a.* from (
select max(Score) as Score,Province from RZ_ExamineePK
group by Province
) a
left join RZ_ExamineePK b on a.score=b.score and a.Province=b.Province
------解决方案--------------------
自己敲的....不过我也用prompt
------解决方案--------------------
工具格式化是这样的
SELECT *
FROM RZ_ExamineePK a
WHERE EXISTS ( SELECT 1
FROM ( SELECT MAX(Score) AS Score ,
Province
FROM RZ_ExamineePK
GROUP BY Province
) b
WHERE a.score = b.score
AND a.province = b.province )
