如何使用Oracle SQL獲取數據的衰減模式/趨勢？

Question

我怎樣才能得到結果只爲那些月度數據在下降模式/趨勢？

並且數據如下;

ID JAN FEB MAR APR MAY JUN 
112 50 45 40 35 30 20 
113 30 30 30 30 30 30 
114 20 25 20 20 20 20 
115 45 50 60 60 30 30 

預期輸出;

ID JAN FEB MAR APR MAY JUN 
112 50 45 40 35 30 20 
115 45 50 60 60 30 30 

謝謝！

Answer 1

SELECT * 
FROM your_table 
WHERE JAN > JUN 

或

SELECT * 
FROM your_table 
WHERE JAN > FEB 
AND FEB > MAR 
AND MAR > APR 
AND APR > MAY 
AND MAY > JUN 

Answer 2

看來，你要找的是什麼

SELECT * 
    FROM SOME_TABLE 
    WHERE JAN > FEB OR 
     FEB > MAR OR 
     MAR > APR OR 
     APR > MAY OR 
     MAY > JUN 

好運。
