是否有办法这样做:

 select Name, sum(Exceptions) exceptions from Results i
 where exceptions > 0
 group by (Name)

在计算结果的实地中,我正在对0的所有记录进行过滤

我正在发现一个错误,即“综合功能的有效使用”

最佳回答
SELECT Name, SUM(Exceptions) AS exceptions
FROM Results AS r
GROUP BY (Name)
HAVING SUM(Exceptions) > 0
问题回答
select Name, sum(Exceptions) exceptions from Results i
group by (Name)
HAVING SUM(Exceptions) > 0

HAVING是适用于aggregated的一个条款。 成果汇编。
