使用数据透视

declare @t table 
(
    driver varchar(20), 
    roadband varchar(20), 
    category varchar(20), 
    points int 

) 

INSERT INTO @T VALUES('Dan' ,'20 Mph','CAT1',58)

我需要转动上Roadband和Category显示多个值成列在SQL Server ..使用数据透视

我已经写了查询..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

现在如何通过公路带来每个类别的枢纽。

请大家帮忙。

如果您发布的代码， XML或数据样本，**请在文本编辑器中突出显示这些行，然后单击编辑器工具栏上的“代码示例”按钮（“{}”）以精确地格式化和语法突出显示它！ –

从你的问题，我不知道你在想列，应该是什么行，所以我写了这两个问题，我希望他们中的一个回答你的问题是什么值：

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
