如何將不相關的列添加到組中？

Question

我想通過查詢將以下非相關列添加到組，但我不希望結果按以下列分組。

case when ito.Rating<=25    then 'e - Very Unfavourable' 
when ito.rating>=30 and Rating<=45 then 'd - Unfavourable' 
when ito.rating = 50    then 'c - Neutral' 
when ito.rating>=55 and Rating<=70 then 'b - Favourable' 
when ito.Rating>=75     then 'a - Very Favourable' 
end as ComplexFav 

我該怎麼做呢？

目前導致「列‘ItemOrganisations.Rating全腳本’，因爲它不是在聚合函數或GROUP BY子句包含在選擇列表中無效。」：

select o.Name, 

case when ito.Rating<=25    then 'e - Very Unfavourable' 
    when ito.rating>=30 and Rating<=45 then 'd - Unfavourable' 
    when ito.rating = 50    then 'c - Neutral' 
    when ito.rating>=55 and Rating<=70 then 'b - Favourable' 
    when ito.Rating>=75     then 'a - Very Favourable' 
    end as ComplexFav, 


COUNT(i.ID) as 'total count', 
sum(mc.Circulation/ 1000) as Imps, 

sum(case when ito.Rating >50 then 1 else 0 end) as 'fav count', 
sum(case when ito.rating <50 then 1 else 0 end) as 'unfav count', 
sum(case when ito.Rating =50 then 1 else 0 end) as 'neu count', 

avg(CONVERT(decimal(6,2),ito.Rating)) as 'Av Rating P', 

(sum(case when ito.Rating >50 then 1.0 else 0.0 end)/count(i.ID) * 100) as 'fav P', 
(sum(case when ito.rating < 50 then 1.0 else 0.0 end)/count(i.ID) * 100) as 'unfav P', 
(sum(case when ito.Rating =50 then 1.0 else 0.0 end)/count(i.ID) * 100) as 'neu P', 

sum(case when ito.Rating >50 then mc.Circulation/1000 else 0 end) as 'fav Imps', 
sum(case when ito.rating <50 then mc.Circulation/1000 else 0 end) as 'unfav Imps', 
sum(case when ito.Rating =50 then mc.Circulation/1000 else 0 end) as 'neu Imps', 

CASE WHEN ISNULL(sum(mc.circulation/1000),0) = 0 THEN 0 ELSE (sum(case when ito.Rating > 50 then mc.Circulation /1000 else 0.0 end)/(sum(mc.Circulation/1000)) * 100) END as 'fav Imps P', 
CASE WHEN ISNULL(sum(mc.circulation/1000),0) = 0 THEN 0 ELSE (sum(case when ito.rating < 50 then mc.Circulation /1000 else 0.0 end)/(sum(mc.Circulation/1000)) * 100) END as 'unfav Imps P', 
CASE WHEN ISNULL(sum(mc.circulation/1000),0) = 0 THEN 0 ELSE (sum(case when ito.Rating = 50 then mc.Circulation /1000 else 0.0 end)/(sum(mc.Circulation/1000)) * 100) END as 'neu Imps P'

剛猜測，沒有自己嘗試。

如果CASE語句保證返回只有一個值，你可以嘗試把它包在MAX（）函數。 max（）也適用於字符串AFAIK。

max(case when ito.Rating<=25    then 'e - Very Unfavourable' 
when ito.rating>=30 and Rating<=45 then 'd - Unfavourable' 
when ito.rating = 50    then 'c - Neutral' 
when ito.rating>=55 and Rating<=70 then 'b - Favourable' 
when ito.Rating>=75     then 'a - Very Favourable' 
end) as ComplexFav
