Question

我想从名字中删除诸如Dr.，Jr.的头衔。 Regexp_replace应该搜索并删除Jr先生，搜索应该不区分大小写，最终输出不应包含.或,或名称中的多余空格。

select regexp_replace('DR. Mr. Mr Dr Radha Jr Jr. Krishnan Jr.','(Dr|Mr|Jr)(\W|\w|$|,)',1,0,'i') 
from dual

我收到无效的号码错误。

您忘记了在pattern和1之间替换什么

shopify.api_version.VersionNotFoundError.

Answer 2

以下查询将删除多个空白并也修剪前导空格：

SELECT TRIM(REGEXP_REPLACE(
         REGEXP_REPLACE('DR. Mr. Mr Dr Radha Jr Jr. Krishnan Jr.', '(Dr|Mr|Jr)(\W|\w|$|,)', '', 1, 0, 'i')
       , ' {2,}', ' ')) AS "Result"
FROM Dual

它将返回结果为Radha Krishnan

Answer 3

您的解决方案缺少两个方面。

更重要的是，您可以从名称中删除开头的“标题”：

select regexp_replace('DR. Mr. Mr Dr Dradha Jr Jr. Mrishnan Jr.','(Dr|Mr|Jr)(\W|\w|$|,)','',1,0,'i') 
from dual

返回不期望的结果

dha  shnan

补救措施是在标题之后仅允许非单词字符（\W）和行尾（$）。< / p>

如果您在标题前加了可选空格或行首（^）（em），则摆脱了第二个问题，即删除标题后剩下的空格

select regexp_replace('DR. Mr. Mr Dr Dradha Jr Jr. Mr, Mrishnan Jr.',
  '( *|^)(Dr|Mr|Jr)(\W|$)','',1,0,'i') 
from dual

Dradha Mrishnan

Regexp_replace返回了无效的数字
