【问题描述】：

我对一些总帐科目和按月计算的总和有以下查询：

Select Month, [41100],[42000],[45100],[42200],[42300],[42400],[45200],
        [45205]

        from ( Select ACC_0 , (CONVERT(NUMERIC(12,2),(AMTLED_0))) as Amount , MONTH(ACCDAT_0) as Month
        from x3v6.CICPROD.GACCENTRYD with(nolock)

        where YEAR(ACCDAT_0) = YEAR(GETDATE())

        ) as s1

        PIVOT (SUM(Amount)  FOR ACC_0 IN ([41100],[42000],[45100],[42200],[42300],[42400],[45200],
        [45205])) as pivot1

这会产生以下结果集：

 Month  41100   42000   45100   42200   42300   42400   45200   45205


    1   3857806.91  19987.61    49876.84    49078.59    2173.63     NULL    375.00  68.52

    3   4311142.03  8594.31     44220.72    33850.08    3116.75    141.00   1917.50 NULL

    7   4549485.41  10054.92    61607.99    65136.00    1531.66    186.30   265.50  NULL
    8   4239075.39  16917.10    43012.02    51591.25    1538.01    1690.91  350.00  NULL
    9   4331439.41  39248.15    56368.41    74928.00    1858.82     694.32  160.00  66.00
    10  3673909.02  12283.42    38928.66    28608.00    NULL        NULL    120.00  NULL

我想在右侧的一列中按每一行获得一个 TOTAL 计数。我将如何使用 PIVOT 语法完成此操作？我尝试使用分组集，但它对我不起作用。

版本是 SQL Server 2012。

谢谢

【参考方案1】：

一种简单的方法是不使用 PIVOT，而是将 SUM 聚合与 CASE 表达式一起使用。

SELECT  Month,
        SUM(CASE WHEN ACC_0 = '41100' THEN Amount END) AS [41100],
        SUM(CASE WHEN ACC_0 = '42000' THEN Amount END) AS [42000],
        SUM(CASE WHEN ACC_0 = '45100' THEN Amount END) AS [45100],
        SUM(CASE WHEN ACC_0 = '42200' THEN Amount END) AS [42200],
        SUM(CASE WHEN ACC_0 = '42300' THEN Amount END) AS [42300],
        SUM(CASE WHEN ACC_0 = '42400' THEN Amount END) AS [42400],
        SUM(CASE WHEN ACC_0 = '45200' THEN Amount END) AS [45200],
        SUM(CASE WHEN ACC_0 = '45205' THEN Amount END) AS [45205],
        SUM(Amount) AS [Total]
FROM    (SELECT ACC_0,
                (CONVERT(NUMERIC(12,2),(AMTLED_0))) AS Amount,
                MONTH(ACCDAT_0) AS Month
         FROM   x3v6.CICPROD.GACCENTRYD WITH (NOLOCK)
         WHERE  YEAR(ACCDAT_0) = YEAR(GETDATE())
                -- only get the ACC_0 values you need so Total is correct
                AND ACC_0 IN ('41100','42000','45100','42200','42300','42400','45200','45205')
        ) AS s1 
GROUP BY Month
