初始跳過小於4個字符的單詞

Question

我有一個關於initcap的問題。 是否可以創建一個initcap語句來跳過小於4個字符的單詞更改。

因爲我必須將少於4個字符的單詞改回正常，在完成initcap之後。
所以我認爲mabye有可能創建一個函數/過程/觸發器，只會跳過單詞？這些單詞被用在像「Son En Breugel」這樣的地名中，中間的「En」必須變得更低。
字符串的第一個字母並不需要改變，只有一個空格後的第一個小字（就像在字符串中間）

我開始創建一個過程，但它需要一點微調

的*不需要所有的字符串與INITCAP被改回改變
* INITCAP與xDutch格式

--Still需要找到方法來「s轉換」改變• ，我想我已經用這個腳本刪除了記錄？

有人可以幫助我嗎？

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

對潛在問題可能沒有簡單的答案。我假設你正在嘗試正確地使用荷蘭語的地址，這個問題與昨天的this other question有關。

結合的問題，至少有三個特殊情況至今：

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

INITCAP甚至NLS_INITCAP('...', 'NLS_SORT=xDutch')未能妥善處理。在開始編碼之前，您應該收集所有要求。這些是荷蘭大寫字母的唯一規則，還是還有更多？

到目前爲止發佈的答案可能有助於解決一個特定的例外。但是，你不可能簡單地結合正則表達式並解決所有問題。您可能想在這裏採取更自上而下的方法。

UPDATE

基於wolφi的idead，可以使用所有現有的名稱來暴力破解的問題。 95％的時間單獨工作。使用this link電子表格中的431名稱，可以構建一個包含所有25個特例的列表。

運行該語句一次，以建立一個DECODE表達式來處理所有非平凡的情況：

--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 
    ',nls_initcap(name, ''NLS_SORT=xDutch''))'

使用從該聲明的結果建立一個UPDATE這樣的：

Answer 2

如果問題是關於荷蘭地名的，是否可以選擇查找表？根據歐盟統計局的統計，在NUTS5/LAU2級別有418個「Gemeenten」。一個列表可在http://epp.eurostat.ec.europa.eu/portal/page/portal/nuts_nomenclature/local_administrative_units。如果這是不可接受的，你至少可以驗證你的程序與正式名單...
