SQLite錯誤 - 錯誤使用aggregate：sum（）

Question

您好我正在濫用follwing查詢的aggregate：sum（）錯誤。這有什麼問題。

> Select storeid, supplierid, ordernumber, inwardnumber, returnid, 
> taxinvoiceno, ordervalue, sum(CASHPAID) as 'CASHPAID', balancedue, 
> paidamt, paiddate, sum(ADJUSTMENT) as 
> ADJUSTMENT,ordervalue+sum(ADJUSTMENT) as total from 
> supplierpaymentstabledb where storeid = 10008 and total!=CASHPAID 
> group by inwardnumber 

Answer 1

是良好實踐的問題，你應該把所有的非聚集列group by子句。然後，在彙總列條件應該在having條款，而不是一個where條款：

Select storeid, supplierid, ordernumber, inwardnumber, returnid, 
     taxinvoiceno, ordervalue, sum(CASHPAID) as CASHPAID, balancedue, 
     paidamt, paiddate, sum(ADJUSTMENT) as ADJUSTMENT, 
     ordervalue + sum(ADJUSTMENT) as total 
from supplierpaymentstabledb 
where storeid = 10008 
group by storeid, supplierid, ordernumber, inwardnumber, returnid, 
     taxinvoiceno, ordervalue, balancedue, 
     paidamt, paiddate 
having total <> CASHPAID;
