Question

我的问题就像this question，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

我该怎么做？

       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'
