sql - 如何在 SQL 问题 Oracle 中除以值

Question

我如何制作第五列来划分我从 Vikt 和 AntalOrder 获得的值？

/*

*/
select O08T1.pickdate,
          O08T1.divcode,
sum(O08T1.calcwght) as Vikt,
sum(O08T1.calcvol) as Volym,
count(O08T1.ordno) as AntalOrder

from O08T1  
group by O08T1.pickdate, O08T1.divcode
order by Pickdate DESC

Answer 1

虽然你可以使用显式除法，但我猜那ordno是 never NULL。如果是这样，您可以将查询表述为：

select O08T1.pickdate, O08T1.divcode,
       sum(O08T1.calcwght) as Vikt, sum(O08T1.calcvol) as Volym,
       count(*) as AntalOrder,
       avg(O08T1.calcwght) as avg_vikt
from O08T1  
group by O08T1.pickdate, O08T1.divcode
order by Pickdate DESC
