从遵循模糊模式SQLNetezza的字符串中提取序列号

Question

请我有一条日志消息，其中包含一个模糊模式的序列，很难像下面的一样遵循

|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         |

我需要从字符串中提取序列号，如下面的

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

我使用regexp_replace()得到了上述查询，但它错过了其中一些

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

Answer 1

尝试

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

它应该会给你寻找的结果

SERIAL
