MYSQL错误 'unknown column in having clause'

Question

查询如下，我收到错误:

SELECT a.name
FROM author a, catalog c
WHERE a.authorid = c.authorid
AND c.bookid IN (
    SELECT bookid
    FROM orderdetails
    GROUP BY bookid
    HAVING sum(quantity) = (
        SELECT max(sum(quantity))
        FROM orderdetails
    )
);

下表由图书经销商维护。

AUTHOR (author-id:int, name:string, city:string, country:string)
PUBLISHER (publisher-id:int, name:string, city:string, country:string)
CATALOG (book-id:int, title:string, author-id:int, publisher-id:int, category-id:int, year:int, price:int)
CATEGORY (category-id:int, description:string)
ORDER-DETAILS (order-no:int, book-id:int, quantity:int)

问题是:

四。查找销量最高的书的作者。

Answer 1

您可能需要一个中间组

  select a.name 
  from author a
  inner join catalog c on  a.authorid=c.authorid 
  and c.bookid in (select bookid 
            from orderdetails 
            group by bookid 
            having sum(quantity) = (
                select max( sum_quantity) from (
                  select sum(quantity) sum_quantity
                  from orderdetails 
                  group by bookid 
                )
            );
