PERCENTILE_CONT函數拋出錯誤

Question

我有這個疑問，我正在嘗試引入非靜態值到PERCENTILE_CONT：

SELECT perf2.REVIEW_PERIOD 
    , PERCENTILE_CONT(goalsASP.GOAL*.01) WITHIN GROUP (ORDER BY AVG_AMT ASC) ast75 
FROM repDB.TBL_PERFORMANCE perf2 JOIN 
     pz.CATEGORY C on perf2.DEPTCAT = C.id JOIN 
     repDB.TBL_GOALS_MATRIX goalsASP ON C.NAME = goalsASP.DIMENSION_Y 
             and perf2.REVIEW_PERIOD = goalsASP.SNAP_NAME 
             and goalsASP.DIMENSION_X = 'asp' 
GROUP BY perf2.REVIEW_PERIOD 

拋出的錯誤是：

ORA-30497: Argument should be a constant or a function of expressions in GROUP BY. 30497. 00000 - "Argument should be a constant or a function of expressions in GROUP BY."

這是一個查看，它工作正常時goalsASP.GOAL*.01.75.75和我有一個存儲過程中提供一個列作爲參數工作得很好，所以我有點在我在這裏做錯了一種損失。

Answer 1

明白了。這不是Percentile_Cont的問題，這是一個正確分組的問題。

要解決我孤立goalsASP.GOAL

SELECT perf2.REVIEW_PERIOD 
    , goalsASP.GOAL 
FROM repDB.TBL_PERFORMANCE perf2 JOIN 
     pz.CATEGORY C on perf2.DEPTCAT = C.id JOIN 
     repDB.TBL_GOALS_MATRIX goalsASP ON C.NAME = goalsASP.DIMENSION_Y 
             and perf2.REVIEW_PERIOD = goalsASP.SNAP_NAME 
             and goalsASP.DIMENSION_X = 'asp' 
GROUP BY perf2.REVIEW_PERIOD 

那麼很明顯，我需要還GROUP BY goalsASP.GOAL。

這樣，那麼，答案是：尷尬

SELECT perf2.REVIEW_PERIOD 
    , PERCENTILE_CONT(goalsASP.GOAL*.01) WITHIN GROUP (ORDER BY AVG_AMT ASC) ast75 
FROM repDB.TBL_PERFORMANCE perf2 JOIN 
     pz.CATEGORY C on perf2.DEPTCAT = C.id JOIN 
     repDB.TBL_GOALS_MATRIX goalsASP ON C.NAME = goalsASP.DIMENSION_Y 
             and perf2.REVIEW_PERIOD = goalsASP.SNAP_NAME 
             and goalsASP.DIMENSION_X = 'asp' 
GROUP BY perf2.REVIEW_PERIOD, 
     goalsASP.GOAL 

樣，我沒有之前看到的，但疲憊的眼睛錯過這個東西。
