Scenes:
There is a field in the table that stores one or more URL addresses. Now you need to replace the IP and port numbers in all URLs in the field with new IP and port numbers.
The original data is as shown below:
Need to replace ftps://192.168.85.222:990 with http://233.146.24.111:9001
Run SQL:
select
old_fj,
regexp_replace(old_fj,'ftps://(?:(?:25[0-5]|2[0-4]\\d|[01]?\\d?\\d)\\.){3}(?:25[0-5]|2[0-4]\\d|[01]?\\d?\\d)\:([1-9][0-9]{0,3}|[1-5][0-9]{4}|6[0-4][0-9]{3}|65[0-4][0-9]{2}|655[0-2][0-9]|6553[0-5])','http://233.146.24.111:9001/buckets/jsscssmx') as new_fj

Summarize:
The most important thing is to identify the IP plus port in the data through regular expressions
The regular expression is as follows:
(?:(?:25[0-5]|2[0-4]\\d|[01]?\\d?\\d)\\.){3}(?:25[0-5]|2[0-4]\\d|[01]?\\d?\\d)\:([1-9][0-9]{0,3}|[1-5][0-9]{4}|6[0-4][0-9]{3}|65[0-4][0-9]{2}|655[0-2][0-9]|6553[0-5])
