Question

我正在尝试选择最低值和最高值，或者在表格中的值之前或之后。例如，我试图选择包含百分比（PERCEN_TOT）的行，大于我在搜索中传递的值。示例：如果我在＆＃34; PERCEN_TOT＆＃34;中传递搜索值如果等于23，则应返回列，并且以下值或更早（根据研究）分别为＆＃34; LINE＆＃34;柱。什么可以研究，是APPROX_COUNT_DISTINCT Oracle 12的功能，但是，我刚刚安装了Oracle 11。有人可以帮帮我吗？

表格为：

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
);

目录：

以下似乎可以满足您的要求：

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);

如果你需要找回不同的东西，请改变它。
