需要帮助说明产品的平均价格指数,我有成本和销售价格
原标题:need help to figure out average price markup on products, I have cost and selling price

我有一个数据库,有产品,成本和销售价格。

我想编写一份简单的报告,将列出类似的成本计算,并列出数额。

然后,我将利用这一标记对新产品进行标识。

因此,我的数据库希望:

productid, costPrice, sellingPrice
123, 9.99, 14.99

www.un.org/Depts/DGACM/index_spanish.htm 我的新产品只有成本价格,因此,我要说明平均销售价对成本相同的产品,并将其应用于新产品。

问题回答

首先,你的标记是(Selling/Cost)。

页: 1

如果你希望检查一下,那就应该像现在这样。

SELECT CostPrice, AVG(SellingPrice/CostPrice)
FROM Table
GROUP BY CostPrice

除非你使用价格范围,否则,这不会在意义上产生许多成果。

某些产品可能比其他产品有更大的标记,但价格仍然不变。 你可能希望以稍微不同的方式对待这一问题。

为了与你的工作范围相配合,我也许会去掉像我这样的东西。

DECLARE @Range INT
SET @Range = 5

SELECT  CEILING(CostPrice / @Range) * @Range,
        AVG(SellingPrice / CostPrice)
FROM    @Table
GROUP BY CEILING(CostPrice / @Range)

或形成一个含有你价格幅度的表格,并按这些幅度分类。

类似于

DECLARE @Table TABLE(
        CostPrice FLOAT,
        SellingPRice FLOAT
)

INSERT INTO @Table SELECT 0.99, 14.99
INSERT INTO @Table SELECT 4.99, 9.99
INSERT INTO @Table SELECT 9.99, 14.99
INSERT INTO @Table SELECT 19.99, 9.99

DECLARE @Ranges TABLE(
        StartVal FLOAT,
        EndVal FLOAT
)

INSERT INTO @Ranges SELECT 0, 5
INSERT INTO @Ranges SELECT 5, 10
INSERT INTO @Ranges SELECT 10, 15
INSERT INTO @Ranges SELECT 15, NULL

SELECT  ISNULL(r.EndVal, r.StartVal),
        AVG(t.SellingPRice / t.CostPrice)
FROM    @Ranges r LEFT JOIN
        @Table t    ON  t.CostPrice > r.StartVal AND (t.CostPrice <= r.EndVal OR r.EndVal IS NULL)
GROUP BY ISNULL(r.EndVal, r.StartVal)
