SQL Server 2008会計年度別注文

Question

SQlサーバーで以下のSQLを使用して会計年度別に注文したいが、 '無効な列名' MONTH ''というエラーメッセージが表示される。私はあなたが私の下のSQLを変更するのを助けることができるのだろうかと思います。ありがとう！

SELECT 'Closed Home' AS STATUS, 
    right(CONVERT(VARCHAR(8), Closed_Dt, 3),5) as "MONTH", 
    COUNT(Home_ID) COUNT 
FROM Home 
GROUP BY HOME_STATUS,right(CONVERT(VARCHAR(8), Closed_Dt, 3),5) 
HAVING Facility_STATUS IN ('CLOSED') 

UNION 

SELECT 'New Placement' AS STATUS, 
right(CONVERT(VARCHAR(8), EFFECT_DT, 3),5) AS "MONTH", 
COUNT(CLT_NBR) AS COUNT 
FROM STATUS S 
GROUP BY right(CONVERT(VARCHAR(8), EFFECT_DT, 3),5)  
ORDER BY status, 
    case "MONTH" when '07/15' then 1 
       when '08/15' then 2 
       when '09/15' then 3 
       when '10/15' then 4 
       when '11/15' then 5 
       when '12/15' then 6 
       when '01/16' then 7 
       when '02/16' then 8 
       when '03/16' then 9 
       when '04/16' then 10

    FROM STATUS S 
    GROUP BY right(CONVERT(VARCHAR(8), EFFECT_DT, 3),5)

        when '06/16' then 12 
     end 

Answer 2

あなたはそれがORDER BY句でだにもかかわらず、CASE式でエイリアスを参照できないので、エラーを取得しています。

これは動作するはずです：

... 
case right(CONVERT(VARCHAR(8), Closed_Dt, 3),5) 
... 

Answer 3

を、あなたは `CASE`文のことをしないでください

SELECT * FROM (
    SELECT 'Closed Home' AS STATUS, 
      RIGHT(CONVERT(VARCHAR(8),Closed_Dt,3),5) AS "MONTH", 
      COUNT(Home_ID) COUNT 
    FROM Home 
    GROUP BY HOME_STATUS, 
      RIGHT(CONVERT(VARCHAR(8),Closed_Dt,3),5) 
    HAVING Facility_STATUS IN ('CLOSED') 
    UNION 
    SELECT 'New Placement' AS STATUS, 
      RIGHT(CONVERT(VARCHAR(8),EFFECT_DT,3),5) AS "MONTH", 
      COUNT(CLT_NBR) AS COUNT 
    FROM STATUS S 
    GROUP BY RIGHT(CONVERT(VARCHAR(8),EFFECT_DT,3),5) 
) t 
ORDER BY status, 
     CASE "MONTH" 
      WHEN '07/15' THEN 1 
      WHEN '08/15' THEN 2 
      WHEN '09/15' THEN 3 
      WHEN '10/15' THEN 4 
      WHEN '11/15' THEN 5 
      WHEN '12/15' THEN 6 
      WHEN '01/16' THEN 7 
      WHEN '02/16' THEN 8 
      WHEN '03/16' THEN 9 
      WHEN '04/16' THEN 10 
      WHEN '05/16' THEN 11 
      WHEN '06/16' THEN 12 
     END
