SQLite错误 - 错误使用aggregate：sum（）

Question

您好我正在滥用follwing查询的aggregate：sum（）错误。这有什么问题。

> 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

是良好实践的问题，你应该把所有的非聚集列group by子句。然后，在汇总列条件应该在having条款，而不是一个where条款：

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;
