sql - 从字符串 SQL Netezza 中提取序列号

Question

请我需要一个可以从 Logmsg 中提取序列号的查询，困难的是它不遵循特定模式，没有固定的分隔符，并且序列长度总是不一样

|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 as change. serial :T5D7S18802909825, user:ahmed.o.haraz       |
|Customer Receive CPE Indoor as change. serial :T5D7S18802909830, user:ahmed.o.haraz       |
|Customer Receive CPE Indoor. serial ZTERRTHJ9303771, user:Mohamed.E176246                 |
|Customer Returned CPE. serial :21530369847SKA011094, user:ahmed.o.haraz                   |

结果将如下所示:

|Serial              |
|--------------------|
|21530369847SKA011094|
|21530369847SK9078291|
|T5D7S18802909825    |
|T5D7S18802909830    |
|ZTERRTHJ9303771     |
|21530369847SKA011094|

一种方法是 regexp_replace() ，但您对以下内容有不同的格式 serial .所以:

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