初始跳过小于4个字符的单词

Question

我有一个关于initcap的问题。 是否可以创建一个initcap语句来跳过小于4个字符的单词更改。

因为我必须将少于4个字符的单词改回正常，在完成initcap之后。
所以我认为mabye有可能创建一个函数/过程/触发器，只会跳过单词？这些单词被用在像“Son En Breugel”这样的地名中，中间的“En”必须变得更低。
字符串的第一个字母并不需要改变，只有一个空格后的第一个小字（就像在字符串中间）

我开始创建一个过程，但它需要一点微调

的*不需要所有的字符串与INITCAP被改回改变
* INITCAP与xDutch格式

--Still需要找到方法来“s转换”改变• ，我想我已经用这个脚本删除了记录？

有人可以帮助我吗？

create or replace PROCEDURE Location_Name_Routine IS 
    BEGIN 
     DELETE 
      FROM Location 
      WHERE Name LIKE '%[^0-9a-zA-Z]%'; 
     UPDATE Location 
      set Name = nls_initcap(Name, 'NLS_SORT=xDutch'); 
     UPDATE Location 
      SET Name = REGEXP_REPLACE(Name,' En',' en'); 
     UPDATE Location 
      SET Name = REGEXP_REPLACE(Name,' Van',' van'); 
     UPDATE Location 
      SET Name = REGEXP_REPLACE(Name,' De',' de'); 
     UPDATE Location 
      SET Name = REGEXP_REPLACE(Name,' Den',' den'); 
     UPDATE Location 
      SET Name = REGEXP_REPLACE(Name,' Over','over'); 
     UPDATE Location 
      SET Name = REGEXP_REPLACE(Name,' Aan',' aan'); 
     UPDATE Location 
      SET Name = REGEXP_REPLACE(Name,' Bij',' bij');  
    END;  

Answer 1

对潜在问题可能没有简单的答案。我假设你正在尝试正确地使用荷兰语的地址，这个问题与昨天的this other question有关。

结合的问题，至少有三个特殊情况至今：

'S GRAVENHAGE => 's Gravenhage 
IJSLAND   => IJsland 
SON EN BREUGEL => Son en Breugel 

INITCAP甚至NLS_INITCAP('...', 'NLS_SORT=xDutch')未能妥善处理。在开始编码之前，您应该收集所有要求。这些是荷兰大写字母的唯一规则，还是还有更多？

到目前为止发布的答案可能有助于解决一个特定的例外。但是，你不可能简单地结合正则表达式并解决所有问题。您可能想在这里采取更自上而下的方法。

UPDATE

基于wolφi的idead，可以使用所有现有的名称来暴力破解的问题。 95％的时间单独工作。使用this link电子表格中的431名称，可以构建一个包含所有25个特例的列表。

运行该语句一次，以建立一个DECODE表达式来处理所有非平凡的情况：

--Build decode for UPDATE. 
select 
    --Start the decode 
    'decode(upper(name),'|| 
    --List all the exceptions. Single quotes are a mess, no way around it. 
    listagg(
    --Upper case version to match 
    ''''||upper(replace(column_value, '''', ''''''))|| 
    --Pre-defined init-capped version 
    ''','''||replace(column_value, '''', '''''')||'''' 
    , ','||chr(10) 
) 
    within group (order by column_value) 
    || 
    --Default to NLS_INITCAP

Answer 2

如果问题是关于荷兰地名的，是否可以选择查找表？根据欧盟统计局的统计，在NUTS5/LAU2级别有418个“Gemeenten”。一个列表可在http://epp.eurostat.ec.europa.eu/portal/page/portal/nuts_nomenclature/local_administrative_units。如果这是不可接受的，你至少可以验证你的程序与正式名单...
