SQL PIVOT 不工作

Question

我尝试旋转这个 SQL 部分，但我无法正确地做到这一点，我该如何修复它，请帮我，谢谢

--SizeBreakDown
    SELECT  OPSD.SizeDetailId AS 'SizeDetailId',
            OPSD.SizeSequenceNo AS 'SizeNo',
            OPSD.SizeId AS 'SizeId',
            SZ.SizeName AS 'SizeName',
            OPSD.Quanity AS 'Quanity'
    FROM    OrderPlacementSizeBreakDown AS OPSD
            INNER JOIN Sizes AS SZ ON OPSD.SizeId = SZ.SizeId

PIVOT
(

    FOR IN ([SizeDetailId],[SizeSequenceNo],[SizeId],[SizeName])
) AS opsd;

请检查 pivot 的语法，因为你错过了聚合函数。

PIVOT
(
<aggregation function missing>--Please add appropriate aggregate function here.
    FOR IN ([SizeDetailId],[SizeSequenceNo],[SizeId],[SizeName])
) AS opsd;

您的数据透视查询部分如下所示。

SELECT *
FROM (
    SELECT OPSD.SizeDetailId AS 'SizeDetailId'
        ,OPSD.SizeSequenceNo AS 'SizeNo'
        ,OPSD.SizeId AS 'SizeId'
        ,SZ.SizeName AS 'SizeName'
        ,OPSD.Quanity AS 'Quanity'
    FROM OrderPlacementSizeBreakDown AS OPSD
    INNER JOIN Sizes AS SZ ON OPSD.SizeId = SZ.SizeId
    ) t
PIVOT(Max(ColumnName) FOR IN (
            [SizeDetailId]
            ,[SizeSequenceNo]
            ,[SizeId]
            ,[SizeName]
            )) AS opsd;
