Question

这是我上一个问题的后续问题：sql - min of 9 weeks max of 15 weeks average of 16 weeks

我得到＆＃34;输入参数值window.onload = function＆＃34;当我执行parfait的真棒答案时。

有人可以解释为什么以及如何替换/指定它？

我不想一直手动输入值。

以下是他的代码答案：

Crosstab2 查询

q.Type

UnionAggQ 查询（加入两个交叉表）

下一个交叉表需要另一个查询作为源，特别是ItemCode和分类度量标准列的聚合联合查询：

TRANSFORM SUM(q.AggDetailQty)
SELECT q.ItemCode
FROM UnionAggQuery q
GROUP BY q.ItemCode
PIVOT **q.Type** IN ('AVG 16 WEEKS', 'MIN 9 WEEKS', 'MAX 15 WEEKS');

最终查询

SELECT Detail.ItemCode,
       'AVG 16 WEEKS' AS Metric,
       AVG(Detail.Quantity) AS AggDetailQty
FROM Detail INNER JOIN Header ON Detail.SalesOrderNo = Header.SalesOrderNo
WHERE Header.OrderDate >= DATEADD("ww",-16, Date())
GROUP BY Detail.ItemCode

UNION ALL

SELECT Detail.ItemCode,
       'MIN 9 WEEKS' AS Metric,
       MIN(Detail.Quantity) AS AggDetailQty 
FROM Detail INNER JOIN Header ON Detail.SalesOrderNo = Header.SalesOrderNo
WHERE Header.OrderDate >= DATEADD("ww",-9, Date())
GROUP BY Detail.ItemCode

UNION ALL

SELECT Detail.ItemCode,
       'MAX 15 WEEKS' AS Metric,
       MAX(Detail.Quantity) AS AggDetailQty
FROM Detail INNER JOIN Header ON Detail.SalesOrderNo = Header.SalesOrderNo
WHERE Header.OrderDate >= DATEADD("ww",-15, Date())
GROUP BY Detail.ItemCode

Answer 1

试试这个：

TRANSFORM SUM(q.AggDetailQty)
SELECT q.ItemCode
FROM UnionAggQuery q
GROUP BY q.ItemCode
PIVOT q.Metric IN ('AVG 16 WEEKS', 'MIN 9 WEEKS', 'MAX 15 WEEKS');

sql - 需要澄清＆＃34; q.type＆＃34;在交叉表/聚合上的平均/最小/最大
