Question

我在SQL Server中遇到问题，我不知道如何修复。从下面的查询和输出我需要生成以下度量：大小级别的ATP（可承诺）百分比，即：

有3种尺寸，2种有qtys - 1种没有。如果有任何数量，那么我想返回值＆＃39; 1＆＃39;如果不是＆＃39; 0＆＃39; （CASE声明）
留下2的值为＆＃39; 1＆＃39;和＃0;＆＃39; 0 （2/3）或66％＆＃39;全尺寸ATP＆＃39;

如何使用下面的查询生成该计算？我在COUNT声明中尝试了CASE但没有运气。

感谢帮助。

查询：

    SELECT A.MATERIAL, 
       M.SIZE_LITERAL, 
       DATEPART(mm,AVAIL_DATE) AS 'MONTH',
      CASE 
            WHEN A.AVAIL_QTY IS NULL 
            THEN '0'
            ELSE A.AVAIL_QTY
       END AS 'AVAIL_QTY', 
      COUNT(AVAIL_QTY) AS 'COUNT_ATP_QTY',
      COUNT(AVAIL_QTY)/COUNT(*) AS 'ATP %'
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, 
         AVAIL_DATE, 
         A.AVAIL_QTY,
         A.STOCK_CATEGORY

SELECT @@ROWCOUNT

结果：

MATERIAL           SIZE_LITERAL MONTH       AVAIL_QTY                               COUNT_ATP_QTY ATP %
------------------ ------------ ----------- --------------------------------------- ------------- -----------

AA2721             L            8           45                                      1             1
AA2721             M            8           51                                      1             1

这应该这样做 - 你需要在结果中为每个材料获得一行，因为你正在计算聚合（ATP），并且NULL不会被计算，所以你不需要使用CASE，你可以算一下非NULL并除以总计数。

SELECT COUNT(NULLIF(A.AVAIL_QTY, 0)) / COUNT(*) * 100 AS [Full Size ATP]
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

SQL Server计算或使用聚合的指标
