从遵循模糊模式 SQL Netezza 的字符串中提取序列号 [英] extract serial from string that follow fuzzy pattern SQL Netezza

问题描述

请我有一条日志消息，其中包含一个模糊模式的序列，如下图所示

please I Have a log message that contains a serial with a fuzzy pattern that hard to follow like the below

|LogMsg                                                                                    |
|------------------------------------------------------------------------------------------|
|Customer Receive CPE Indoor. serial 21530369847SKA011094, user:ahmed.o.haraz              |
|Customer Receive CPE Indoor as change. serial :21530369847SK9078291, user:Abdullah.M160275|
|Customer Receive CPE Indoor. serial:ZTERRT1H9202990                                       |
|Customer Receive CPE Indoor. serial 21530369847SKB333996 .UserName :TEDST.mohamed.badry   |
|Customer Receive CPE Indoor as change. serial :21530373727skc298302, user:Frass.m195577   |
|Customer Receive CPE Indoor. serial 21530369847SKA267112 .UserName :seller.160002         |

我需要从如下所示的字符串中提取序列号

I need to extract the Serial from the string like the below

|Serial|
|21530369847SKA011094|
|21530369847SK9078291|
|ZTERRT1H9202990     |
|21530369847SKB333996|
|21530373727skc298302|
|21530369847SKA267112|

我使用 regexp_replace() 得到了提到的查询，但它错过了其中的一些

I got the mentioned query using regexp_replace() but it missed some of them

select replace(replace(regexp_extract(logmsg, 'serial [^,]+'), 'serial ', ''), ':', '')

推荐答案

尝试

select get_value_varchar(
        regexp_extract_all_sp(logmsg,
          '(serial\s*:?)([^,\s]+)'),3) as serial
from serial;

它应该给你你正在寻找的结果

It should give you the result you are looking for

        SERIAL
