您好， 我收到一个错误，即grandvisit是一个无效的标识符，我不确定我是否会使用其他标识符。任何关于此的光线都会令人惊叹。因为我不明白为什么它与其他人不同。
答案 0 :(得分：0)
您无法在生成它的同一alias子句中引用select个名称。
SELECT Sum(aerosolvisit + hazvisit + hvvisit + hlopvisit
+ plvisit + miniloadvisit + aprvisit + apr2visit
+ aprawkvisit) AS grandvisit
要计算grandratio您正在使用以下表达式，该表达式使用别名grandvisit
SELECT CASE
WHEN Sum(grandtotal) = 0 THEN 0
WHEN Sum(grandvisit) = 0 THEN 0
ELSE Sum(grandtotal) / Sum(grandvisit)
END AS grandratio
您可以使用派生表来执行此操作
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
注意：您正在使用旧式外部联接（+=）。最好使用更易读的Right/Left连接
