需要将去年的结果提取到库存使用报告中

Question

我有一份库存使用报告，其中包含上一年的交易记录。现在我有当年的结果。我要使用的正确日期语法是什么？

以下是我目前拥有的今年的信息我正在使用今年的获取日期函数并需要它来计算相同的信息，但按月细分去年的信息。

SELECT OITM.ItemCode, OITM.ItemName AS 'Description', OITM.CardCode AS 
'Vendor',
SUM(OITW.OnHand) AS 'On Hand', SUM(OITW.OnOrder) AS 'On Order', 
SUM(OITW.IsCommited) AS 'Committed',

(SUM(OITW.OnHand)+SUM(OITW.OnOrder)-SUM(OITW.IsCommited)) AS 'Available', 
OITM.AvgPrice AS 'Unit Cost',(SUM(OITW.OnHand)*OITM.AvgPrice) AS 'Value $',
(SELECT SUM(OINM.OutQty) FROM OINM WHERE OINM.TransType <> '67' AND 
YEAR(OINM.DocDate)=((year, -1, GETDATE()) AND OINM.ItemCode = OITM.ItemCode 
GROUP BY

OINM.ItemCode) AS 'Prev. Year',

Answer 1

我的建议是稍微缩短原始查询。如果我没有完全错的话，可以这样写：

WITH 
  OINM_Base (ItemCode, [Month], OutQty) AS (
    SELECT 
      ItemCode,
      CASE GROUPING(MONTH(DocDate))
        WHEN 1 THEN 0 ELSE MONTH(DocDate)
      END,
      SUM(OutQty)
    FROM OINM
    WHERE TransType <> '67' AND YEAR(DocDate) = YEAR(GETDATE()) -- change this for the previous year
    GROUP BY ItemCode, ROLLUP(MONTH(DocDate))
  ),
  OINM_Data (ItemCode, [Year], JAN, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, [DEC]) AS (
    SELECT ItemCode, [0], [1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12]
    FROM OINM_Base
    PIVOT (SUM(OutQty) FOR [Month] IN ([0], [1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12])) pvt
  ),
  OITW_Data (ItemCode, [On Hand], [On Order], [Committed]) AS (
    SELECT ItemCode, SUM(OnHand), SUM(OnOrder), SUM(IsCommited)
    FROM OITW
    GROUP BY ItemCode
  )
SELECT
  tm.ItemCode,
  tm.ItemName AS [Description],
  tm.CardCode AS Vendor,
  tw.[On Hand], tw.[On Order], tw.[Committed],
  tw.[On Hand] + tw.[On Order] - tw.[Committed] AS Available,
  tm.AvgPrice AS [Unit Cost],
  tw.[On Hand] * tm.AvgPrice AS [Value $],
  nm.[Year], nm.JAN, nm.FEB, nm.MAR, nm.APR, nm.MAY, nm.JUN, nm.JUL, nm.AUG, nm.SEP, nm.OCT, nm.NOV, nm.[DEC]
FROM OITM tm
  INNER JOIN OITW_Data tw ON tm.ItemCode = tw.ItemCode
  LEFT OUTER JOIN OINM_Data nm ON tm.ItemCode = nm.ItemCode;

其工作原理如下：

OINM 中的数据仅限于相关年份，每月对 OutQty 值求和并创建年份的总计，标记为月份编号 0（CTE OINM_Base).使用 PIVOT 查询，将出现在不同行上的总和转换为列 (CTE OINM_Data)。 OITW 数据的聚合也是单独完成的 (CTE OITW_Data)。

OINM_Data 和 OITW_Data 最终与构建来自 OITM 的主要行的数据相结合。到这里，最后的计算就完成了(Available and Value $).

现在，要将查询更改为 return 前一年，只需更改一件事（请参阅我的评论“将此更改为前一年” ), 即:

YEAR(GETDATE()) 必须替换为 YEAR(GETDATE()) - 1。

需要将去年的结果提取到库存使用报告中
