Question

我有一个问题：

SELECT Strtbmovie.id_parent,
       Strtbuser.Name  as 'Name',
       Strtbmovie.Name as Movie,
       sum(Strtbmovieatt.CountBeginWatch),
       sum(Strtbmovieatt.CountEndWatch),
       sum(Strtbmovieatt.CountBeginTest),
       sum(Strtbmovieatt.CountEndTest),
       max(Strtbmovieatt.CountTest)
FROM   Strtbmovie
       INNER JOIN Strtbmovieatt
         ON Strtbmovie.Idmovie = Strtbmovieatt.Idmovie
       INNER JOIN Strtbuser
         ON Strtbmovieatt.Iduser = Strtbuser.Iduser
GROUP  BY Strtbmovie.Name,
          Strtbuser.Name,
          Strtbmovie.id_parent

如何在知名id_parent？

的名称中替换此查询列id_parent

Answer 1

您必须使用Strtbmovie表INNER JOIN添加额外的ON Strtbmovie.id_parent = StrtbmovieParent.Idmovie，并按实际名称添加组，如下所示：

SELECT StrtbmovieParent.Name as ParentName,
       Strtbuser.Name  as 'Name',
       Strtbmovie.Name as Movie,
       sum(Strtbmovieatt.CountBeginWatch),
       sum(Strtbmovieatt.CountEndWatch),
       sum(Strtbmovieatt.CountBeginTest),
       sum(Strtbmovieatt.CountEndTest),
       max(Strtbmovieatt.CountTest)
FROM   Strtbmovie
       INNER JOIN Strtbmovieatt
         ON Strtbmovie.Idmovie = Strtbmovieatt.Idmovie
       INNER JOIN Strtbuser
         ON Strtbmovieatt.Iduser = Strtbuser.Iduser
       INNER JOIN Strtbmovie as StrtbmovieParent
         ON Strtbmovie.id_parent = StrtbmovieParent.Idmovie
GROUP  BY Strtbmovie.Name,
          Strtbuser.Name,
          StrtbmovieParent.Name

需要在SQL Server中替换名称上的id_parent
