Question

我有以下查询;

SELECT      STOCK_CODE,
            dbo.manu_STOCK.DESCRIPTION, 
            QTY_IN_STOCK, 
            Quantity, 
            ForecastDate
FROM        [FS25-w2k8\SQLEXPRESS].sagel50_46772.dbo.SalesForecastLines AS SalesForecastLines1 
INNER JOIN  dbo.manu_STOCK 
    ON      SalesForecastLines1.ProductCode = dbo.manu_STOCK.STOCK_CODE

这会显示以下信息;

STOCK_CODE        DESCRIPTION         QTY_INSTOCK            Quantity      ForecastDate
  523                 gel                  12                   10           01/08/2014
  523                 gel                  12                   10           08/08/2014

我希望能够修改查询，以便显示以下格式

Stock Code Description  WK1  WK2

523           gel        22   22

因此它将在第一个日期对库存和数量进行总和，该列将被称为wk1，第二周 - wk2等。

你能就此提出建议吗？

Answer 1

如果要将结果转动52周，可以使用以下查询。这将使数据转向52周。这只是概念，我无法测试此查询。

SELECT  *  FROM
( SELECT
            dbo.manu_STOCK.STOCK_CODE AS [Stock Code],
            dbo.manu_STOCK.DESCRIPTION, 
            DATEPART(WEEK,[Date]) Wk,
            QTY_IN_STOCK + Quantity AS Stock

  FROM  [FS25-w2k8\SQLEXPRESS].sagel50_46772.dbo.SalesForecastLines AS SalesForecastLines1 
        INNER JOIN  dbo.manu_STOCK 
            ON SalesForecastLines1.ProductCode = dbo.manu_STOCK.STOCK_CODE
) AS Source

按代码，desc，年份和星期分组，然后按一周的总和计算一年中的每周（根据每年的开始/结束而增加额外的一周。

按标题SQL对记录进行分组
