如何在 SQL 问题 Oracle 中除以值

问题描述

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

解决方法

尽管您可以使用显式除法，但我猜测 ordno 永远不会是 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
