试试这个解决方案;它使用RATIO_TO_REPORT。

SELECT   y.share_holder_id
,        y.shareholders
,        y.portion_of_co
,        y.company_name
FROM    (SELECT x.share_holder_id
         ,      x.shareholders
         ,      RATIO_TO_REPORT(x.share_amount) 
                OVER (PARTITION BY x.company_id) portion_of_co
         ,      c.name                           company_name
         FROM  (SELECT  sh.share_holder_id
                ,       sh.first_name
                        || ' '
                        || sh.last_name     shareholders
                ,       s.company_id
                ,       SUM(t.share_amount) share_amount
                FROM    trades t
                INNER JOIN share_holders sh
                ON         t.share_holder_id = sh.share_holder_id
                INNER JOIN shares        s
                ON         s.share_id = t.share_id
                GROUP BY   sh.share_holder_id
                ,          sh.first_name 
                           || ' '
                           || sh.last_name
                ,          s.company_id
                ) x
         INNER JOIN companies c
         ON         x.company_id = c.company_id
         ) y
WHERE    y.portion_of_co > 0.005
ORDER BY y.share_holder_id
