SQL Question
sql - need clarification "q.type" on crosstab/aggregates for average/min/max
It's a follow-up question for my previous question:sql - min of 9 weeks max of 15 weeks average of 16 weeks
I'm getting "Enter parameter value of
q.TypeCan someone explain why and how can I substitute/specify it?
I don't want to manually enter value all the time..
The below is his code answer:
Crosstab2 Query
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');
UnionAggQ Query (joining both crosstabs)
Next crosstab needs another query as the source, specifically a union query of aggregates by ItemCode with categorical Metric column:
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
Final Query
SELECT t1.*, t2.*
FROM CrossTab1 t1
INNER JOIN CrossTab2 t2
ON t1.ItemCode = t2.ItemCode
