如何在oracle SQL中比较十六进制值

我有一个十六进制值的列，我想和下面的其他十六进制值进行比较，但我得到的结果不准确

SELECT vc_vin_vis_start_range FROM ok_dc.gms3_vc_mme_vin_si_detail
   WHERE TO_NUMBER(vc_vin_vis_start_range) >= TO_NUMBER('100001');

是否有一种方法可以比较查询中的两个十六进制值

感谢您的帮助

使用

TO\u数字（十六进制值，'xxxxxxxxx'）

（其中

x

s的数字是十六进制

VARCHAR2

列的最大长度）：

Oracle安装程序：

CREATE TABLE ok_dc.gms3_vc_mme_vin_si_detail ( vc_vin_vis_start_range ) AS
  SELECT '1'      FROM DUAL UNION ALL
  SELECT 'FFFFF'  FROM DUAL UNION ALL
  SELECT '100001' FROM DUAL UNION ALL
  SELECT '100002' FROM DUAL UNION ALL
  SELECT NULL     FROM DUAL;

SELECT vc_vin_vis_start_range
FROM ok_dc.gms3_vc_mme_vin_si_detail
WHERE TO_NUMBER(vc_vin_vis_start_range, 'xxxxxxxxxx') >= TO_NUMBER('100001', 'xxxxxxxxxx');

VC_VIN_VIS_START_RANGE
----------------------
100001
100002

查询：

CREATE TABLE ok_dc.gms3_vc_mme_vin_si_detail ( vc_vin_vis_start_range ) AS
  SELECT '1'      FROM DUAL UNION ALL
  SELECT 'FFFFF'  FROM DUAL UNION ALL
  SELECT '100001' FROM DUAL UNION ALL
  SELECT '100002' FROM DUAL UNION ALL
  SELECT NULL     FROM DUAL;

SELECT vc_vin_vis_start_range
FROM ok_dc.gms3_vc_mme_vin_si_detail
WHERE TO_NUMBER(vc_vin_vis_start_range, 'xxxxxxxxxx') >= TO_NUMBER('100001', 'xxxxxxxxxx');

VC_VIN_VIS_START_RANGE
----------------------
100001
100002

输出：

CREATE TABLE ok_dc.gms3_vc_mme_vin_si_detail ( vc_vin_vis_start_range ) AS
  SELECT '1'      FROM DUAL UNION ALL
  SELECT 'FFFFF'  FROM DUAL UNION ALL
  SELECT '100001' FROM DUAL UNION ALL
  SELECT '100002' FROM DUAL UNION ALL
  SELECT NULL     FROM DUAL;

SELECT vc_vin_vis_start_range
FROM ok_dc.gms3_vc_mme_vin_si_detail
WHERE TO_NUMBER(vc_vin_vis_start_range, 'xxxxxxxxxx') >= TO_NUMBER('100001', 'xxxxxxxxxx');

假设列

vc\u vin\u vis\u start\u range

没有空值，那么我将执行以下操作：

SELECT vc_vin_vis_start_range FROM ok_dc.gms3_vc_mme_vin_si_detail
   WHERE TO_NUMBER(vc_vin_vis_start_range, 
                   rpad('x', length(vc_vin_vis_start_range) , 'x'))
      >= TO_NUMBER('100001', 'xxxxxx');

rpad（）

函数根据要转换的每个值构建十六进制格式。

假设列

vc\u vin\u vis\u start\u range

没有空值，那么我将执行以下操作：

SELECT vc_vin_vis_start_range FROM ok_dc.gms3_vc_mme_vin_si_detail
   WHERE TO_NUMBER(vc_vin_vis_start_range, 
                   rpad('x', length(vc_vin_vis_start_range) , 'x'))
      >= TO_NUMBER('100001', 'xxxxxx');

rpad（）？有多少？@标签大小变量列
vc\u vin\u vis\u start\u range
中的所有数字大小（位数）是否完全相同？多少？@司机尺码不一，非常感谢。看起来这两个解决方案都在运行我之所以接受另一个解决方案，只是因为在它上面创建函数索引很容易。非常感谢你的时间。谢谢，非常感谢。看起来这两个解决方案都在运行我之所以接受另一个解决方案，只是因为在它上面创建函数索引很容易。非常感谢你的时间。谢谢
