如何在同一天列中添加主题而不是多个

Question

我有以下记录。我希望在星期一列中显示所有科目的科目，周一出现开始时间和结束时间。我该怎么做？

SELECT t.teacher_name, tci.class_name, tsb.Subject_Name, tdn.DaysName, 
       tss.subject_start, tss.subject_end
FROM   tblsubjectSchedule tss
INNER JOIN tblsubjects tsb ON tss.subject_id = tsb.Idx
INNER JOIN tblclassinfo tci ON tss.class_id = tci.Idx
INNER JOIN tbldaysnames tdn ON tss.days_id = tdn.Idx 
INNER JOIN tblteacher t ON tss.techer_id = t.Idx
WHERE tss.class_id = 2 AND t.school_id = 1

您的附件并不完全清楚。你会在结果上忽略teacher_name吗？ 在您的屏幕截图中，您还没有包含＆＃39; samad teacheer＆＃39;周一结果。您希望查询仅用于星期一日期吗？

如果你只专注于课程，日期和日期，我就得到了以下内容。请参阅附件。让我知道它是否适合您并接受我的回答。  

SELECT t1.class_name,t1.daysname,
       subject_name =REPLACE( (SELECT  (subject_name+'-start:'+CONVERT(VARCHAR, subject_start, 120)+'-End:'+CONVERT(VARCHAR, subject_end, 120)) AS [data()]
           FROM [practice].[dbo].[test] t2
          WHERE t2.daysname = t1.daysname
          ORDER BY subject_name
            FOR XML PATH('')
            ), ' ', ';')
      FROM [practice].[dbo].[test] t1
      GROUP BY daysname,class_name ;

您还可以将教师名称添加到计划列：请参阅附件

SELECT t1.class_name,t1.daysname,
       schedule =REPLACE( (SELECT  (teacher_name+'-'+subject_name+'-start:'+CONVERT(VARCHAR, subject_start, 120)+'-End:'+CONVERT(VARCHAR, subject_end, 120)) AS [data()]
           FROM [practice].[dbo].[test] t2
          WHERE t2.daysname = t1.daysname
          ORDER BY subject_name
            FOR XML PATH('')
            ), ' ', ';')
      FROM [practice].[dbo].[test] t1
      GROUP BY daysname,class_name ;

以下是仅针对＆＃39;星期一＆＃39;

的查询

SELECT t1.class_name,t1.daysname,
       schedule =REPLACE( (SELECT  (teacher_name+'-'+subject_name+'-start:'+CONVERT(VARCHAR, subject_start, 120)+'-End:'+CONVERT(VARCHAR, subject_end, 120)) AS [data()]
           FROM [practice].[dbo].[test] t2
          WHERE t2.daysname = t1.daysname
          ORDER BY subject_name
            FOR XML PATH('')
            ), ' ', ';')
      FROM [practice].[dbo].[test] t1 where daysname='Monday'
      GROUP BY daysname,class_name ;
