Question

我已经搜索了该站点，并且我认为我做得正确，但是已经晚了，现在我必须脑子死了。这个PIVOT SQL有什么问题？

SELECT  AccountNum  
        , MONTH(MAX(DealBookDate)) AS Month  
        , YEAR(MAX(DealBookDate))  AS Year  
FROM  
(  
    SELECT AccountNum   
         , MONTH(MAX(DealBookDate)) AS mth   
         , YEAR(MAX(DealBookDate))  AS yr   
         , DealBookDate  
    FROM vehicle.sales  
    WHERE accountnum IN  
    ('R1', 'R2', 'R3', 'R4', 'R5', 'R6', 'R7', 'R8', 'R9', 'R10', 'R11',   
'R12', 'R13', 'R14', 'R15')  
    GROUP BY  AccountNum  
            , DealBookDate  
) AS SourceTable  
PIVOT  
(  
  COUNT(DealBookDate)  
    FOR AccountNum  
    IN  
    (  
    R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15
    )  
)  
AS PivotTable;

这是我收到的错误消息：

消息207，级别16，状态1，第31行无效的列名称 “ AccountNum”。消息207，级别16，状态1，第32行无效列名称为“ DealBookDate”。消息207，级别16，状态1，第33行无效列名称“ DealBookDate”。

请对我好一点，毕竟是星期一。

尝试以下方式

   SELECT   *  
        FROM  
        (  
            SELECT * 
            FROM vehicle.sales  
            WHERE accountnum IN  
            ('R1', 'R2', 'R3', 'R4', 'R5', 'R6', 'R7', 'R8', 'R9', 'R10', 'R11',   
        'R12', 'R13', 'R14', 'R15')             
        ) AS SourceTable  
        PIVOT  
        (  
          COUNT(DealBookDate)  
            FOR AccountNum  
            IN  
            (  
            [R1], [R2], [R3], [R4], [R5], [R6],[R7],[R8],[R9], [R10], [R11], [R12], [R13], [R14], [R15]
            )  
        )  
        AS PivotTable;
