，C“感谢您的快速响应我将第二行更改为：，Count（不同的ProductID）作为NROF产品，该产品的退货量为7HM 3倍，这更接近我的期望for@debuggerlikeanother我看到你修改了源数据。如果回扣代码是三个字母，那么我所提出的第一个解决方案显然会起作用。产品名称不是唯一的吗？如果不是，你可以考虑将产品名称和产品名称分组在一起。呃。（后面的选项只是为了在查询中显示）.@debuggerlikeanother-此外，如果ProductId是产品表的PK，我将使用它连接到CombinationRebateCode的子查询，而不是产品名称。我相信您的建议可能是我解决方案的基础。但我不知道如何操作和聚合结果透视表中的数据（例如，如果（sum（AMOUNT）==NULL，然后0，否则sum（AMOUNT））并在选择*，[ABC]+[XYZ]+[LOI]作为编解码器，然后按编解码器分组 ID ProductID Product RebateCode Amount 1 123 7HM ABC 1 2 123 7HM XYZ 2 3 124 7HM ABC 10 4 124 7HM XYZ 20 5 125 7HM ABC 100 6 125 7HM XYZ 200 7 125 7HM CEX 3 8 126 2EA ECU 4 8 127 2EA ECU 40 9 128 2EB FBA 5 9 129 2EB FBA 50 10 130 2EB FBA 500 CREATE TABLE #ProductSales(ID SMALLINT, ProductID int, Product varchar(6), RebateCode varchar(4), Amount int) GO INSERT INTO #ProductSales select 1, 123, '7HM', 'ABC', 1 union all select 2, 123, '7HM', 'XYZ', 2 union all select 3, 124, '7HM', 'ABC', 10 union all select 4, 124, '7HM', 'XYZ', 20 union all select 5, 125, '7HM', 'ABC', 100 union all select 6, 125, '7HM', 'XYZ', 200 union all select 7, 125, '7HM', 'CEX', 3 union all select 8, 126, '2EA', 'ECU', 4 union all select 8, 127, '2EA', 'ECU', 40 union all select 9, 128, '2EB', 'FBA', 5 union all select 9, 129, '2EB', 'FBA', 50 union all select 10, 130,'2EB', 'FBA', 500 GO Product nrOfProducts rebateCodeCombination SumAmount ABC CEX ECU FBA XYZ 7HM 2 ABC, XYZ 33 11 0 0 0 22 7HM 1 ABC, CEX, XYZ 303 100 3 0 0 200 2EB 3 FBA 555 0 0 0 555 0 2EA 2 ECU 44 0 0 44 0 0 ..
