T-SQL Pivot 添加总行

Question

我有一个数据透视语句，它可以生成我需要的内容，除非我想在底部添加一个“总计”行。有没有人能解释一下？

SELECT TheProvider AS [PC],
    ISNULL([201204],0) AS [201204],
    ISNULL([201205],0) AS [201205], -- 2012/13
    ISNULL([201206],0) AS [201206], -- 2012/13
    ISNULL([201207],0) AS [201207], -- 2012/13
    ISNULL([201208],0) AS [201208], -- 2012/13
    ISNULL([201209],0) AS [201209], -- 2012/13
    ISNULL([201210],0) AS [201210], -- 2012/13
    ISNULL([201211],0) AS [201211], -- 2012/13
    ISNULL([201212],0) AS [201212], -- 2012/13
    ISNULL([201301],0) AS [201301], -- 2012/13
    ISNULL([201302],0) AS [201302], -- 2012/13
    ISNULL([201303],0) AS [201303], -- 2012/13

    ISNULL([201304],0) AS [201304], -- 2013/14
    ISNULL([201305],0) AS [201305], -- 2013/14

    ISNULL([201403],0) AS [201403]  -- 2013/14

            ELSE LEFT([OC (CoP)], 3)
            END AS TheProvider

        ,COUNT(*) AS TheAmount

            END
        ,LEFT([OC (CoC)], 3)
        ,LEFT([Arrival Date], 6)
    HAVING (LEFT([Arrival Date], 6) > '201203')
        OR (LEFT([Arrival Date], 6) > '201203')

    ) UP

            )) AS pvt

您应该可以使用ROLLUP 添加总计行。这会将您的代码更改为以下内容：

SELECT coalesce(TheProvider, 'Total') AS [PC],
    sum(ISNULL([201204],0)) AS [201204],
    sum(ISNULL([201205],0)) AS [201205], -- 2012/13
    sum(ISNULL([201206],0)) AS [201206], -- 2012/13
    sum(ISNULL([201207],0)) AS [201207], -- 2012/13
    sum(ISNULL([201208],0)) AS [201208], -- 2012/13
    sum(ISNULL([201209],0)) AS [201209], -- 2012/13
    sum(ISNULL([201210],0)) AS [201210], -- 2012/13
    sum(ISNULL([201211],0)) AS [201211], -- 2012/13
    sum(ISNULL([201212],0)) AS [201212], -- 2012/13
    sum(ISNULL([201301],0)) AS [201301], -- 2012/13
    sum(ISNULL([201302],0)) AS [201302], -- 2012/13
    sum(ISNULL([201303],0)) AS [201303], -- 2012/13

    sum(ISNULL([201304],0)) AS [201304], -- 2013/14
