我需要转向Roadband和Category ..

我写了查询..需要一些帮助..

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

根据你的问题，我不确定你想要的列中的值和行中应该是什么，所以我写了两个查询，希望其中一个回答你的问题：

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

使用pivot在sql server中的列中显示多个值
