我需要轉動上Roadband和Category顯示多個值成列在SQL Server ..使用數據透視

我已經寫了查詢..需要一些幫助..

select * from 
(
    select 
    Driver, ROADBAND, category,SUM(points) as Points 
    from @t 
    where DRIVER is not null 
    group by DRIVER ,ROADBAND,CATEGORY 
) main 
pivot 
(
    sum(Points) 
    for ROADBAND in ([20 Mph],[30 Mph],[40 Mph],[50 Mph],[60 Mph],[70 Mph]) 
) pq

現在如何通過公路帶來每個類別的樞紐。

請大家幫忙。

如果您發佈的代碼， XML或數據樣本，**請在文本編輯器中突出顯示這些行，然後單擊編輯器工具欄上的「代碼示例」按鈕（「{}」）以精確地格式化和語法突出顯示它！ –

從你的問題，我不知道你在想列，應該是什麼行，所以我寫了這兩個問題，我希望他們中的一個回答你的問題是什麼值：

SELECT * 
FROM (
      SELECT category 
        , roadband 
        , SUM(points) points_per_category_roadband 
      FROM @t 
      GROUP BY 
        category, roadband 
) tbl 
PIVOT 
(
    SUM(points_per_category_roadband) FOR roadband IN ([20 Mph],[30 Mph],[40 Mph],[50 Mph],[60 Mph],[70 Mph]) 
) pvt 


SELECT * 
FROM (
      SELECT roadband 
        , category 
        , SUM(points) points_per_category_roadband 
      FROM @t 
      GROUP BY 
        roadband, category 
) tbl 
PIVOT 
(
    SUM(points_per_category_roadband) FOR category IN ([CAT1],[CAT2],[CAT3]) 
) pvt
