Question

我一直在努力完成以下查询，但似乎无法让它发挥作用。

我想知道是否有人能够明白我做错了什么？

MSSQL Server 2012。

我已经测试了连接和一些子查询，你可以从它自己的查询中看到它们并且它们工作正常。

有什么想法吗？

SELECT b.CLIENT_NAME
  ,e.VARIABLE_NAME
  --,[TOTAL]
  --,AVG(a.TOTAL) AS [Total KPI]
   --, (SUM(d.WEEK1_NET)+SUM(d.WEEK2_NET)+SUM(d.WEEK3_NET)+SUM(d.WEEK4_NET))AS [Net Sales]
  ,SUM(
case 
  when a.GRAPH_ID =  1 then 100/(SUM(d.WEEK1_NET)+SUM(d.WEEK2_NET)+SUM(d.WEEK3_NET)+SUM(d.WEEK4_NET))*SUM(a.TOTAL) 
  when a.GRAPH_ID =  2 then 100/ (SUM(d.WEEK1_GROSS)+SUM(d.WEEK2_GROSS)+SUM(d.WEEK3_GROSS)+SUM(d.WEEK4_GROSS))*SUM(a.TOTAL)

  else AVG(a.TOTAL) 
end) AS Project_KPI 
FROM [MMAUDIT].[dbo].[MMA_KPIVAR_DAT] AS a

LEFT JOIN MMA_CLIENT_MST AS b
ON a.CLIENT_ID= b.CLIENT_ID

LEFT JOIN MMA_SITE_MST AS c
ON a.CLIENT_ID= c.CLIENT_ID
AND a.SITE_ID= c.SITE_ID

LEFT JOIN MMA_SALESPERF_DAT AS d
ON a.CLIENT_ID= d.CLIENT_ID
AND a.SITE_ID= d.SITE_ID
AND a.AUDIT_DATE= d.AUDIT_DATE

LEFT JOIN MMA_KPIVAR_MST As e
ON a.CLIENT_ID= e.CLIENT_ID
AND a.CHART_ID=e.CHART_ID
AND a.GRAPH_ID= e.GRAPH_ID
AND a.VARIABLE_ID= e.VARIABLE_ID

WHERE a.CLIENT_ID= 18
AND a.AUDIT_DATE BETWEEN '2017-01-01' AND '2017-07-01'
--AND a.GRAPH_ID IN (3,4,5,6)
GROUP BY b.CLIENT_NAME
  ,e.VARIABLE_NAME
  --,[TOTAL]'

谢谢约翰

您不能拥有嵌套的SUM或其他聚合。一个简单的例子是here。

SUM(
case 
  when a.GRAPH_ID =  1 then 100/(SUM(d.WEEK1_NET)+SUM(d.WEEK2_NET)+SUM(d.WEEK3_NET)+SUM(d.WEEK4_NET))*SUM(a.TOTAL) 
  when a.GRAPH_ID =  2 then 100/ (SUM(d.WEEK1_GROSS)+SUM(d.WEEK2_GROSS)+SUM(d.WEEK3_GROSS)+SUM(d.WEEK4_GROSS))*SUM(a.TOTAL)

  else AVG(a.TOTAL) 
end)

是一个问题，因为它将SUM与SUM和AVG嵌套，并且计算不明确。最简单的解决方法是在子查询中使用内部SUM：SUM（d.WEEK1_NET）等，然后使用主查询中case语句中的值。
