Question

我有一张表（提名），看起来像：

Year  Category      Artist-Name                Title          Album
1980  AlbumOfYear   Michael Jackson            Thriller       Thriller
1980  ...           ...
1981  ...           ...
1982  ...           ...

我正在尝试开发一个查询，该查询将从用户输入的年份中返回最多指定的Artist-Name，然后按降序返回列表。这样的事情可能吗？（为查询创建新列并从查询中排名）

类似

Rank   Artist              Nominations
1      Michael Jackson     3
2      Billy Joel          2

Answer 1

SET @fromyear = 1980;
SET @toyear = 1992;


SET @rank = 0;


SELECT 
@rank:=@rank+1 as rank, 
noms.artist, 
noms.nominations
FROM
    (
    SELECT COUNT(*) as nominations, `Artist-Name` as artist 
    FROM `Nominations`
    WHERE `Year` BETWEEN @fromyear AND @toyear
    GROUP BY `Artist-Name`
    ORDER BY COUNT(*) DESC
    ) as noms;

Answer 2

以这种方式使用GROUP BY：

SET @rank=0;
SELECT @rank:=@rank+1 as rank, Artist-Name as Artist, count(*) as Nominations
WHERE Year = 1980
GROUP BY Artist-Name
ORDER BY Nominations DESC

Answer 3

这应该适用于oracle。

select rank() over(order by nominations desc),artist,nominations from   
(select artist,count(nominations) nominations from nominations where year between :loweryear and :higheryear group by artist);

SQL查询从年份范围返回“最多指定”，作为列表（使用新列）
