根據輸入的值，在表中輸入最低近似值（前一個）或更高（後續）

我試圖選擇最低和最高值，或者在表中的值之前或之後。例如，我試圖選擇包含百分比（PERCEN_TOT）的行，大於我在搜索中傳遞的值。示例：如果我將「PERCEN_TOT」中的搜索值傳遞等於23，則應該返回列，並且以下值或更早（根據研究）分別爲「LINE」列的3或4。有什麼可以研究的，是APPROX_COUNT_DISTINCT是Oracle 12的函數，不過我剛安裝了Oracle 11. 有誰能幫幫我嗎？根據輸入的值，在表中輸入最低近似值（前一個）或更高（後續）

表是：內容

CREATE TABLE INVOICE 
(
    INV_NUMPED VARCHAR2(6 BYTE), 
    INV_NUMITE NUMBER, 
    INV_CODPRO VARCHAR2(10 BYTE), 
    INV_QTDITE NUMBER, 
    INV_VALITE NUMBER, 
    INV_VALTOT NUMBER, 
    SUM_VTOTAL NUMBER, 
    PERCEN_TOT NUMBER, 
    LINE   NUMBER 
);

下似乎得到你，你要問什麼：

SELECT * 
    FROM INVOICE a 
    WHERE a.PERCEN_TOT = (SELECT MAX(PERCEN_TOT) 
         FROM INVOICE 
         WHERE PERCEN_TOT < 23) 
UNION ALL 
SELECT a.* 
    FROM INVOICE a 
    WHERE a.PERCEN_TOT = (SELECT MIN(PERCEN_TOT) 
          FROM INVOICE 
          WHERE PERCEN_TOT < 23);

改變它周圍，如果你需要找回一些不同的東西。
