如何在 SQL Server 2008 查询中显示订单履行情况

Question

我正在想办法在 SQL Server 2008 数据库上通过销售订单 table 运行并获得打开对零件的需求，按到期日订购，然后查看采购订单 table 并按 PO 履行销售订单，并按到期日订购 PO 供应。同时，我需要显示哪些采购订单正在履行销售订单。

例如：

SO table

SO#     DueDate     Part Number  Required QTY
---------------------------------------------
100     9/3/16      1012          2
101     9/12/16     1012          1
107     10/11/16    1012          4
103     10/17/16    1012          7

PO table:

PO#     DueDate     Part Number  Ordered QTY
--------------------------------------------
331     9/1/16      1012          1
362     9/2/16      1012          1
359     9/24/16     1012          5
371     10/1/16     1012          3
380     10/10/16    1012          10

有了这个数据，我想看到这个结果：

SO#  DueDate     Part Number  Required QTY  PO number  QTY Used  QTY Remain
 --------------------------------------------------------------------------
100  9/3/16      1012          2             331         1         0 
100  9/3/16      1012          1             362         1         0
101  9/12/16     1012          1             359         1         4
107  10/11/16    1012          4             359         4         0
103  10/17/16    1012          7             371         3         0
103  10/17/16    1012          7             380         4         6

我以前做过这个销售订单履行流程，但没有达到分解哪些 PO（s）正在履行订单的程度，只是达到总结所有开放供应的程度，然后运行ning通过并从每个销售订单中减去供应量以获得运行ning 剩余供应量。

非常感谢您的帮助。

我发现了一个有点奇怪的解决方案，希望对你有帮助。也许以后我可以优化它，但现在我 post 它是：

;WITH cte AS (
    SELECT 1 as l
    UNION ALL
    SELECT l+1
    FROM cte
    WHERE l <= 1000000
), SO_cte AS (
    SELECT  *,
            ROW_NUMBER() OVER (ORDER BY DueDate ASC) as rn
    FROM SO s
    CROSS JOIN cte c
    WHERE c.l <= s.[Required QTY]
), PO_cte AS (
    SELECT  *,
            ROW_NUMBER() OVER (ORDER BY DueDate ASC) as rn
    FROM PO p
    CROSS JOIN cte c
    WHERE c.l <= p.[Ordered QTY]
), almost_done AS (
    SELECT DISTINCT     
            s.SO#,
            s.DueDate,
            s.[Part Number],
            p.PO#,
            s.[Required QTY],
            p.[Ordered QTY]
    FROM SO_cte s
    LEFT JOIN PO_cte p
        ON p.rn = s.rn
), final AS (
    SELECT  *,
            ROW_NUMBER() OVER (ORDER BY DueDate) AS RN
    FROM almost_done
)

SELECT  f.SO#,
        f.DueDate,
        f.[Part Number],
        f.[Required QTY],
        f.PO#,
        CASE WHEN f.[Ordered QTY]>f.[Required QTY] 
                THEN ISNULL(ABS(f1.[Required QTY]-f1.[Ordered QTY]),f.[Required QTY]) 
                ELSE f.[Ordered QTY] END 
                        as [QTY Used],
        f.[Ordered QTY] - 
        CASE WHEN f1.PO# = f.PO# 
                THEN f1.[Ordered QTY]
                ELSE
                    CASE WHEN f.[Ordered QTY]>f.[Required QTY] 
                            THEN ISNULL(ABS(f1.[Required QTY]-f1.[Ordered QTY]),f.[Required QTY]) 
                            ELSE f.[Ordered QTY] END
         END as [QTY Remain]
FROM final f
LEFT JOIN final f1
    ON f.RN = f1.RN+ 1
        AND (f.SO# = f1.SO# OR f.PO# = f1.PO#)
OPTION(MAXRECURSION 0)

您提供的数据的输出：

SO# DueDate     Part Number Required QTY    PO# QTY Used    QTY Remain
100 2016-09-03  1012        2               331 1           0
100 2016-09-03  1012        2               362 1           0
101 2016-09-12  1012        1               359 1           4
107 2016-10-11  1012        4               359 4           0
103 2016-10-17  1012        7               371 3           0
103 2016-10-17  1012        7               380 4           6
