有什麼方法可以動態地命名Netezza中的pivoted列?在SSMS中,我會使用存儲過程,但是我們新的Netezza框限制了SP的創建。使用CASE語句,我可以使用行號來每月循環每日總和,但是我希望新的列名是實際的任意MONTHID而不是行號(MONTH_ID1包含ROW_NUMBER 1-12和相應的MONTHID)。例如,我在戰略上考慮引用和子查詢,但我無法實現它。Netezza中的動態列命名
select "DAY"
,sum(case when "ROW_NUMBER" = 1 then SUMOFCHGS else null end) as "1"
,sum(case when "ROW_NUMBER" = 2 then SUMOFCHGS else null end) as "2"
,sum(case when "ROW_NUMBER" = 3 then SUMOFCHGS else null end) as "3"
,sum(case when "ROW_NUMBER" = 4 then SUMOFCHGS else null end) as "4"
,sum(case when "ROW_NUMBER" = 5 then SUMOFCHGS else null end) as "5"
,sum(case when "ROW_NUMBER" = 6 then SUMOFCHGS else null end) as "6"
,sum(case when "ROW_NUMBER" = 7 then SUMOFCHGS else null end) as "7"
,sum(case when "ROW_NUMBER" = 8 then SUMOFCHGS else null end) as "8"
,sum(case when "ROW_NUMBER" = 9 then SUMOFCHGS else null end) as "9"
,sum(case when "ROW_NUMBER" = 10 then SUMOFCHGS else null end) as "10"
,sum(case when "ROW_NUMBER" = 11 then SUMOFCHGS else null end) as "11"
,sum(case when "ROW_NUMBER" = 12 then SUMOFCHGS else null end) as "12"
FROM DLYAMTS D
JOIN MONTH_ID1 M ON D.MONTHID = M.MONTHID
GROUP BY 1
ORDER BY 1
我可以想象在未來與列的數目可變這樣做,但我只是在尋找一個一年的月柱的現在。
