SQL 服务器 - 枢轴前的复杂排序?

SQL Server - Complicated sort before pivot?

这个请求可能看起来非常复杂和冗长,所以提前道歉。

我有几个 table:ITEMFINAL_SORT 和 "another" table(在这种情况下,我将使用 CARTON table,但还有其他 table 需要相同的功能)。

我们有一些商品,其中每个单独的 SKU 都采用 [range-style-style].[colour].[size] 格式的单个字符串/“Item”列(例如 AAA-TSHIRT-AA1.RED.S).实际上,在 table 中,SKU 将采用这种格式。一个“范围”(即代码的第一部分,AAA)可以有多种不同尺码的产品类型(例如 T 恤 XS-XL、裤子 28”-38” 等等)

如果我对纸箱 123 执行 SELECT * FROM CARTON,它将 return:

| ITEM                   | QTY| PARENT_CONTAINER | 
|------------------------|----|------------------|
|  A1A-TSHIRTS-AA1.RED.S | 2  | 123              |
|  A1A-TSHIRTS-AA1.RED.M | 2  | 123              |
|  A1A-TSHIRTS-AA1.RED.L | 2  | 123              |
|  B2B-PANTS-CC3.BLUE.32 | 3  | 123              |
|  B2B-PANTS-CC3.BLUE.34 | 3  | 123              |
|  B2B-PANTS-CC3.BLUE.36 | 3  | 123              |

项目 table 是主项目列表,因此它包含所有 SKU colour/size 组合(例如,上面的产品可能有 XS 和 XL,只是没有包装在上面的纸箱中) . FINAL_SORT table 有一个 "SIZE_FINAL_SORT" 列,用于按尺寸逻辑尺寸(XS、S、M、L、XL 等)排序,否则它将按字母顺序排列订单。

这里的事情远远超出了我的技能水平。我需要以一种方式旋转 CARTON 输出,而不是每个 SKU 一行,每个 style/colour 组合有一行,并且旋转的列应该是通用的 "SIZE1, SIZE2, SIZE3...SIZE10" 列,代表可能的尺寸使用 FINAL_SORT table 排序的产品样式,输出如下:

| ITEM                   | SIZE1  | SIZE2  | SIZE3  | SIZE4  | SIZE5  | SIZE6  | PARENT_CONTAINER | 
((size represents)       | XS/28  | S/30   | M/32   | L/34   | XL/36  | -/38   |                  )
|------------------------|--------|--------|--------|--------|--------|--------|------------------|
|  A1A-TSHIRTS-AA1.RED   |(ISNULL)| 2      | 2      | 2      |(ISNULL)|(ISNULL)| 123              |
|  B2B-PANTS-CC3.BLUE    |(ISNULL)|(ISNULL)| 3      | 3      |3       |(ISNULL)| 123              |

当前的 table 完全可以实现吗?我也许可以创建新的 tables 来帮助解决这个问题,但我无法向上面现有的 tables 添加列。

CREATE TABLE testITEM
    (
    [ITEM] NVARCHAR(30) NULL,
    [ITEM_SIZE] NVARCHAR(10) NULL,
    [RANGE] NVARCHAR(3) NULL

试试这个 Pivot 脚本,它会给出你预期的结果

SELECT 
    SUBSTRING(Item,0,CHARINDEX('.',Item)) AS Item,
     MAX([SIZE1 XS/28]) AS [SIZE1 XS/28]
    ,MAX([SIZE2 S/30] ) AS [SIZE2 S/30]
    ,MAX([SIZE3 M/32] ) AS [SIZE3 M/32]
    ,MAX([SIZE4 L/34] ) AS [SIZE4 L/34]
    ,MAX([SIZE5 XL/36]) AS [SIZE5 XL/36]
    ,MAX([SIZE6 -/38] ) AS [SIZE6 -/38]
    ,PARENT_CONTAINER
FROM
(
SELECT * , CASE WHEN JoinCol IN('XS','28')    THEN 'SIZE1 XS/28' 
                WHEN JoinCol IN('S' ,'30')    THEN  'SIZE2 S/30' 
                WHEN JoinCol IN('M' ,'32')  THEN  'SIZE3 M/32' 
                WHEN JoinCol IN('L' ,'34')  THEN  'SIZE4 L/34'   
                WHEN JoinCol IN('XL','36')  THEN 'SIZE5 XL/36' 
                WHEN JoinCol IN('-','38')   THEN 'SIZE6 -/38'  END AS Sizecol
FROM testFINAL_SORT s                
LEFT JOIN
(
SELECT *,
     REVERSE(SUBSTRING(REVERSE(Item),0,CHARINDEX('.',REVERSE(Item)))) AS JoinCol
FROM testCARTON 
)dt
ON dt.JoinCol = s.ITEM_SIZE
) AS SRC
PIVOT
(
SUM(QTY) FOR Sizecol IN ([SIZE1 XS/28],[SIZE2 S/30] ,[SIZE3 M/32] ,[SIZE4 L/34] ,[SIZE5 XL/36],[SIZE6 -/38])
)AS Pvt

WHERE Item IS NOT NULL
GROUP BY SUBSTRING(Item,0,CHARINDEX('.',Item)),PARENT_CONTAINER

结果
