Regex 在oracle-PL/SQL中使用正则表达式查找POBOX

我想使用oracle-PL/SQL中的正则表达式从出现在单词pobox之后的字符串中提取pobox值。 下面是一些例子 I/p

o/p

类似这样的东西可能会帮助您：

WITH the_table AS (SELECT '1. COMPANY (W L L ) POBOX - 24440 DOHA QATAR TEL 4765888' line FROM dual

你试图做什么来解决这个问题？显示您当前拥有的代码。您好，我尝试了类似REGEXP_REPLACE（REGEXP_SUBSTR（第行，[[:digit:][]].[:digit:][-]+[:digit:][]'，INSTR（第行，'POBOX'），“^-”）的方法。。谢谢你的帮助。这与我给出的值配合得很好。。但对于其他一些模式来说，它是失败的。对于低于标准的模式，它是失败的1.CORAL TECH PETER MAYNARD CO BAY Devoux STREETS二楼POBOX N-1000''2。海湾海洋中心-蒙塔古前滨东湾街邮政信箱SS-19084''3。AHMED SAEED DAMMAM 2044 31453邮政信箱011383-KSA''4。MISR压缩机（CO）A-2工业区10号POBOX 1001''5。诺基亚和网络OY，不包括NSN FRANCE POBOX1 3 Karaporti''6。惠普欧洲有限公司POBOX 100-POBOX 100-CH-1217''7。杜蒙·伯格曼·拜德+有限公司，S.C.POBOX456 DELEGACION CUAUHTEMO MX'。。。。。。抱歉，我不知道如何在代码中发布这些值。是的，正则表达式无法处理这些值，因为POBOX现在不仅由数字组成。我们需要知道每一种可能的POBOX格式，才能得出一个常规表达式。我修改了原来的问题，添加了更多的示例。我想现在它涵盖了大部分的组合。@VidyaPandey我刚刚编辑了我的答案，以适应您提供的新数据。它现在正在工作，但不能与数据库中的每个pobox一起工作
