Question

我需要按照演员的所有细节进行分组。意味着我需要所有的列到目前为止我所做的是：

SELECT Actor.Actor_id AS A,(MAX(Movie.M_year))-(MIN(Movie.M_year))AS DIFF
FROM Actor INNER JOIN (Movie INNER JOIN Acted_in ON (Acted_in.Movie_id=Movie.Movie_id))
ON (Actor.Actor_id=Acted_in.Actor_id)
GROUP BY Actor.Actor_id

如何解决此问题并选择所有列？我只能为id列做这个。

Answer 1

你的语法错了。试试这个：

<webHttpBinding>
   <binding name="webBinding">          
   </binding>
</webHttpBinding>

如果您想要更多列，则可以将其添加为：

SELECT Actor.Actor_id AS A,(MAX(Movie.M_year))-(MIN(Movie.M_year))AS DIFF
FROM Actor INNER JOIN Acted_in ON Actor.Actor_id=Acted_in.Actor_id
INNER JOIN Movie ON Acted_in.Movie_id=Movie.Movie_id
GROUP BY Actor.Actor_id

由Actor表
