Question

我最近有一个善良的灵魂协助我创造一个我无法绕过头脑的计算...现在我面临一个额外的问题，如果它是多余的道歉。以下查询适用于WHERE子句中列出的一篇文章。当我尝试从初始MAX中删除SELECT并将WHERE更改为IN然后添加多个选项时，计算失败。以下是每个方案的示例结果查询。

谢谢！

查询：

SELECT MAX(MATERIAL) AS [MATERIAL],
       SUM(COUNT_ATP_QTY)/ CONVERT(FLOAT,COUNT(1)) AS [FULL_SIZE_ATP]
FROM

 (

SELECT A.MATERIAL, 
       M.SIZE_LITERAL, 
       DATEPART(mm,AVAIL_DATE) AS [MONTH],
       ISNULL(a.avail_qty,'0') AS [Avail_Qty],
       COUNT(AVAIL_QTY) AS [COUNT_ATP_QTY]
FROM   VW_MM_SALES_GRID M 
LEFT OUTER JOIN VW_ATP_DOWNLOAD_NOREQCAT A 
ON A.MATERIAL = M.MATERIAL 
AND A.SIZE_LITERAL = M.SIZE_LITERAL
AND A.STOCK_CATEGORY IN ('A60381000','A60382000')
AND A.AVAIL_DATE BETWEEN GETDATE() AND GETDATE() + 90

WHERE  M.MATERIAL ='AA2721' AND  M.ACTIVE_FLAG IS NOT NULL

GROUP BY A.MATERIAL, 
         M.SIZE_LITERAL, 
         A.AVAIL_DATE, 
         A.AVAIL_QTY,
         A.STOCK_CATEGORY
         ) A

一个材料的结果：

 MATERIAL           FULL_SIZE_ATP
------------------ ----------------------
AA2721             0.666666666666667

如果我添加另一篇文章，AA2720：

MATERIAL           FULL_SIZE_ATP
------------------ ----------------------
NULL               0
AA2721             1

AA2720应为0，但AA2721的计算更改，并且AA2720的材料编号也没有填充

谢谢！

我不认为将内部选择语句的等于更改为输入有任何问题，但是如果你删除了“最大”数据，那么在外部查询中，您需要告诉它如何对结果行进行分组。内部查询在其上有一个分组，但外部查询不在您提供的内容中。

SELECT MATERIAL AS [MATERIAL],
SUM(COUNT_ATP_QTY)/ CONVERT(FLOAT,COUNT(1)) AS [FULL_SIZE_ATP]
FROM

(
SELECT A.MATERIAL, 
   M.SIZE_LITERAL, 
   DATEPART(mm,AVAIL_DATE) AS [MONTH],
   ISNULL(a.avail_qty,'0') AS [Avail_Qty],
   COUNT(AVAIL_QTY) AS [COUNT_ATP_QTY]
FROM   VW_MM_SALES_GRID M 
LEFT OUTER JOIN VW_ATP_DOWNLOAD_NOREQCAT A 
ON A.MATERIAL = M.MATERIAL 
AND A.SIZE_LITERAL = M.SIZE_LITERAL
AND A.STOCK_CATEGORY IN ('A60381000','A60382000')
AND A.AVAIL_DATE BETWEEN GETDATE() AND GETDATE() + 90

WHERE  M.MATERIAL in ('AA2721', 'OtherValue') AND  M.ACTIVE_FLAG IS NOT NULL

GROUP BY A.MATERIAL, 
     M.SIZE_LITERAL, 
     A.AVAIL_DATE, 
     A.AVAIL_QTY,
     A.STOCK_CATEGORY

) A
GROUP BY MATERIAL

无法在SQL Server中向子查询添加多个选择
