嵌套的Select语句查询，错误“关键字'GROUP'附近的语法不正确”

Question

我已经阅读了一些与我的错误有关的帖子，但是没有一个解决方案似乎有效。我对SQL很新，所以很抱歉，如果它真的很简单。我有两张桌子

1. 电影广告资源 - 其中包含movie_title，onhand_qty和replacement_price

列

2. NotFlix - 有subscriber_name，queue_nbr和movie_title

我正在尝试加入这两个表来输出每个客户的总重置价格成本，但是当我这样做时会给出上面标题的错误。这是我的代码，提前感谢任何帮助！

SELECT subscriber_name, SUM (replacement_price) as replacement

FROM

(SELECT NotFlix.subscriber_name, NotFlix.movie_title, NotFlix.queue_nbr, MovieInventory.replacement_price

FROM NotFlix 

INNER JOIN MovieInventory

ON NotFlix.movie_title = MovieInventory.movie_title
)

GROUP BY subscriber_name;

Answer 1

您缺少别名：

SELECT AliasNameHere.subscriber_name, SUM (AliasNameHere.replacement_price) as replacement

FROM

(SELECT NotFlix.subscriber_name as subscriber_name, NotFlix.movie_title, NotFlix.queue_nbr, MovieInventory.replacement_price as replacement_price

FROM NotFlix 

INNER JOIN MovieInventory

ON NotFlix.movie_title = MovieInventory.movie_title
) AliasNameHere

GROUP BY subscriber_name;

Answer 2

我只是不知道为什么你在FROM子句中做一个临时表，你可以在这里做一个基本的INNER JOIN，并且可以避免别名的问题：

SELECT NotFlix.subscriber_name, SUM (MovieInventory.replacement_price) as replacement

FROM NotFlix 

INNER JOIN MovieInventory

ON NotFlix.movie_title = MovieInventory.movie_title

GROUP BY subscriber_name;
