*操作：在錯誤行：188列：12

select "CUSIP", "SIDE", TRADEDATE, ACCOUNTNO, SUM("QUANTITY") as CompressedQuantity, 

(case when quantity = 0 THEN 0 ELSE trunc(sum("PRICE"*"QUANTITY")/sum("QUANTITY"),6) END) as AVERAGEPRICE 
from rawtable 
group by "SIDE", "TRADEDATE", "ACCOUNTNO", "CUSIP") 

select CompressedQuantity,"SIDE", "TRADEDATE", "ACCOUNTNO", "CUSIP" FROM compresstable 
; 

Answer 1

您需要檢查的總金額（數量），而不是數量

select "CUSIP", "SIDE", TRADEDATE, ACCOUNTNO, SUM("QUANTITY") as CompressedQuantity, 
    case when sum(quantity) = 0 THEN 0 ELSE trunc(sum("PRICE"*"QUANTITY")/sum("QUANTITY"),6) END as AVERAGEPRICE 
from rawtable 
group by "SIDE", "TRADEDATE", "ACCOUNTNO", "CUSIP" 

Answer 2

您必須將數量添加到您的組。

group by "SIDE", "TRADEDATE", "ACCOUNTNO", "CUSIP", SUM("QUANTITY")
