如何使用SQL Server對行值進行分組？

Question

我想在SQL Server中對相同的yAxisTitle進行分組，下圖顯示了我的數據。

預期結果：

查詢我所用：

select 
    q.questionId, q.questionName, 
    p.perspectiveTitle, x.xAxisTitle, y.yAxisTitle, c.value 
from 
    coaching_questionPerspectiveMap as c 
inner join 
    Coaching_question as q on c.questionId = q.questionId 
inner join 
    Coaching_perspective as p on c.perspectiveId = p.perspectiveId 
inner join 
    coaching_xAxisData x on c.xAxisDataId = x.xAxisDataId 
inner join 
    coaching_yAxisData y on c.yAxisDataId = y.yAxisDataId 
where 
    q.questionId = 14 
    and p.perspectiveId = 1 
order by 
    c.sort 

請提供任何解決辦法嗎？

感謝，

如果你只是想訂購的數據，以便它顯示了在yAxisTitle組，使用：

select 
    q.questionId, q.questionName, 
    p.perspectiveTitle, x.xAxisTitle, y.yAxisTitle, c.value 
from 
    coaching_questionPerspectiveMap as c 
inner join 
    Coaching_question as q on c.questionId = q.questionId 
inner join 
    Coaching_perspective as p on c.perspectiveId = p.perspectiveId 
inner join 
    coaching_xAxisData x on c.xAxisDataId = x.xAxisDataId 
inner join 
    coaching_yAxisData y on c.yAxisDataId = y.yAxisDataId 
where 
    q.questionId = 14 
    and p.perspectiveId = 1 
order by 
    y.yAxisTitle, c.sort
