Sql 比较同一表中的两行

我想比较一个表中两行的值， 该表如下所示。
我想找到-F sku大于正常sku的记录

SKU         ASIN        Price    
CT0144      B013VNZNYU  20.99
CT0144-F    B013VNZNYU  17.64

试试这个

select t1.SKU,t1.ASIN,t1.Price from table as t1 inner join
(
select ASIN, max(price) as price from table group by ASIN
) as t2 
on t1.ASIN=t2.ASIN and t1.price=t2.price 
where t1.SKU like '%-F'

试着这样,

DECLARE @table TABLE (
    SKU VARCHAR(50)
    ,ASIN VARCHAR(50)
    ,Price FLOAT
    )

INSERT INTO @table
VALUES (
    'CT0144'
    ,'B013VNZNYU'
    ,'20.99'
    )
    ,(
    'CT0144-F'
    ,'B013VNZNYU'
    ,'17.64'
    )
    ,(
    'CT0144'
    ,'B013VNZNU'
    ,'10.99'
    )
    ,(
    'CT0144-F'
    ,'B013VNZNU'
    ,'18.64'
    )

SELECT *
FROM @table

SELECT A.ASIN
    ,A.FPrice
    ,B.Normal
FROM (
    SELECT ASIN
        ,MAX(PRICE) AS FPrice
    FROM @table t1
    WHERE SKU LIKE '%F'
    GROUP BY ASIN
    ) A
INNER JOIN (
    SELECT ASIN
        ,MAX(PRICE) AS Normal
    FROM @table t1
    WHERE SKU NOT LIKE '%F'
    GROUP BY ASIN
    ) B ON A.ASIN = B.ASIN
WHERE A.FPrice > B.Normal

内部使用不同的别名连接表，神奇的是doneMySql？PlSql？您使用的是哪个数据库？我知道，但我想要两个比较两个sku onw是正常的，另一个是正常的+'-FAre ASIN值与正常值和-F相同？为什么不将-F移到一个新列？像一面旗帜！
