Question

我有一张存储学生考试成绩的表格。在该表中，我有一个nvarchar列REMARKS;如果获得的标记小于通过标记，系统会在该特定列中将Pass/Fail添加到Remarks。

现在问题是我显示了获得总分的整个结果，并且如果学生已经通过或失败，也会显示基于

之类的查询

If remarks = 'Fail'

并且失败是该考试中的多个科目而不是显示失败否则通过。我搜索并尝试了很多但没有运气。任何人都可以告诉我如何完成它？

谢谢！

更新：到目前为止尝试过：

SELECT 
    StudentName,
    Year,
    ExamType,
    SUM(TotalMarks) AS TotalMarks,
    SUM(ObtainedMarks) AS ObtMarks  
FROM 
    [dbo].[Exam]
WHERE
    ExamType = @Type AND Year = @Year

寻找类似的查询：

CASE WHEN [Remarks] = 'Fail' and having count > 1  THEN 'Fail' ELSE 'Pass' End as 'Status'

Answer 1

以下查询返回＆＃39; fail＆＃39;在ExamType和year中，学生有多个失败

SELECT StudentName
  ,@Year
  ,@Type
  ,Sum(TotalMarks) as TotalMarks
  ,Sum(ObtainedMarks) as ObtMarks  
  ,CASE WHEN Count(CASE WHEN [Remarks] = 'Fail' THEN 1 END) > 1 THEN 'Fail' ELSE 'Pass' End as 'Status'
FROM [dbo].[Exam]
Where ExamType = @Type And Year = @Year
Group by StudentName

学生结果基于使用SQL Server的已通过和失败的备注
