sql - 多行到带有标题名称的单行

Question

我的问题就像这个问题，但我从不同的表中获取数据：

Name   ID  Subject-name    obtained-marks
gumman  9   English              3
gumman  9   Islamic-Studies      4
gumman  9   Pak Studies          3 

我想要这样的输出：

ID   Name   English   Islamic-Studies   Pak-studies
9   gumman   3             4                3

我怎样才能做到这一点？

  (
    min([obtained-marks]) for [Subject-name] in ([English],
                                                 [Islamic-Studies],
                                                 [Pak Studies])
  ) as P

Answer 2

试试这个：

Select s.ID, s.Name, 
       MAX(case WHEN s.SubjectName = 'English'         THEN s.ObtainedMarks end) as 'English',
       MAX(case WHEN s.SubjectName = 'Islamic-Studies' THEN s.ObtainedMarks end) as 'Islamic-Studies',
       MAX(case WHEN s.SubjectName = 'Pak Studies'     THEN s.ObtainedMarks end) as 'Pak-studies'
From Students s
GROUP BY s.ID, s.Name
