Hallo, ich eine Störung erhalte, die grandvisit ist eine ungültige Kennung, und ich bin nicht sicher, ob ich es mit anderen Kennungen entweder bekommen. Jedes Licht, das auf dieses Licht geworfen würde, wäre erstaunlich. Ich kann nicht verstehen, warum es sich von anderen unterscheidet.

Answer 1

Sie können nicht die alias Namen in derselben select Klausel verweisen, wo es generiert wird.

SELECT Sum(aerosolvisit + hazvisit + hvvisit + hlopvisit 
      + plvisit + miniloadvisit + aprvisit + apr2visit 
      + aprawkvisit) AS grandvisit 

grandratio Zur Berechnung Sie den folgenden Ausdruck verwenden, die den Aliasnamen Sie grandvisit

SELECT CASE 
     WHEN Sum(grandtotal) = 0 THEN 0 
     WHEN Sum(grandvisit) = 0 THEN 0 
     ELSE Sum(grandtotal)/Sum(grandvisit) 
     END AS grandratio 

verwendet können abgeleitete Tabelle verwenden diese

SELECT CASE 
     WHEN Sum(grandtotal) = 0 THEN 0 
     WHEN Sum(grandvisit) = 0 THEN 0 
     ELSE Sum(grandtotal)/Sum(grandvisit) 
     END AS grandratio 
From 
(
SELECT Sum(aerosolvisit + hazvisit + hvvisit + hlopvisit 
      + plvisit + miniloadvisit + aprvisit + apr2visit 
      + aprawkvisit) AS grandvisit 
... 
) A
