需要替换SQL Server中名称上的id\u父项

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

如何在此查询中替换名称为knowing id\u parent上的id\u parent列？

您必须使用Strtbmovie.id\u parent=StrtbmovieParent.Idmovie上的Strtbmovie表添加额外的

内部联接，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

您必须在Strtbmovie.id\u parent=StrtbmovieParent.Idmovie

上通过Strtbmovie表

不清楚你在问什么。您想从另一个表或其他地方获取名称吗？如果是的话，你的桌子结构是什么？不清楚你在问什么。您想从另一个表或其他地方获取名称吗？如果是，您的表结构是什么？
