Question

任何人都可以帮我计算一个查询的％份额。任何帮助表示赞赏。

％分享计算：这是我们计算％份额所需的方式。拥有余额的借款人总数> 500000，所有借款人的余额总和除以所有借款人的总和。

(
(
SELECT SUM(OUTSTANDING_BAL)
FROM MyView
GROUP BY BORROWER_NAME
HAVING SUM(OUTSTANDING_BAL) > 500000 -- SUM OF BORROWER HAVING BALANCE > 500000
)
/ -- DIVIDE BY
(SELECT SUM(OUTSTANDING_BAL) FROM MyView) -- TOTAL SUM 
)*100

请帮忙。

提前谢谢。

如果您只想要一个包含此信息的查询，请使用条件聚合：

select (sum(case when outstanding_bal > 500000 then outstanding_bal else 0 end) /
        sum(outstanding_bal)
       ) as ratio
from (select borrower_name, sum(outstanding_bal) as outstanding_bal
      from MyView
      group by borrower_name
     ) b;

这假设借用可能有多个您想要添加的记录。如果您只想考虑与阈值相关的各个行，则查询更简单：

select (sum(case when outstanding_bal > 500000 then outstanding_bal else 0 end) /
        sum(outstanding_bal)
       ) as ratio
from MyView;
