用PLSQL中的REGEXP_REPLACE替換所有實例

我一直試圖用PLSQL中的REGEXP_REPLACE替換給定字符串中圍繞關鍵字POSTPONE的所有文本。用PLSQL中的REGEXP_REPLACE替換所有實例

在存在兩個彼此相鄰的筆記的情況下，只有第一個實例被替換。

下面是我一直在努力

CROWHURA_POSTPONE_26/03/2015_Postpone_1 30/03/2015 00:00:00~CAMERONR_POSTPONE_30/03/2015_Postpone_1 04/04/2015 00:00:00~CAMERONR_NOTES_30/03/2015_waiting on sr results~CHINGD_POSTPONE_04/04/2015_Postpone_1 07/04/2015 00:00:00

的例子我想只與__NOTE_

#CAMERONR_NOTES_30/03/2015_waiting on sr results#

我一直在使用正則表達式的文字是這樣的：

REGEXP_REPLACE(q.comments,'(~|^).{0,10}_POSTPONE_.{1,42}(~|$)','# ')

任何幫助將不勝感激。

編輯：進一步的例子，該更換的需求爲工作：對於這些，我想任何及所有_note_相關文本

適合你嗎？ http://sqlfiddle.com/#!4/9eecb/3139 –

是的，謝謝，那適用於這個例子。我添加了其他的例子，這也需要工作。 – Deamo

而當沒有'_notes_'相關？ –

SQL Fiddle

** **查詢：

select val, 
regexp_replace(val, '(~?([^~]+_NOTES_[^~]+)~?)|(.)','#\2#') x, --keeps the notes part and replaces everything esle with # 
regexp_replace(regexp_replace(val, '(~?([^~]+_NOTES_[^~]+)~?)|(.)','#\2#'),'#{2,}','#') y --removes consecutive #s 
from 
test t

Results：
