Answer 1

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 
;
