如何从 SQL bigquery 中的 URL 中提取 utm_content

Question

I'm trying to extract the utm_content from the URL.

For example:

https:/www.xxxxxx.com/br/pt/yyyyy/example?origin=ALL&destination=ALL&utm_source=salesforce&utm_medium=email&utm_campaign=just_an_example_ok&utm_content= I_would_like_just_this_part_of_the_string

¿How could I extract just the utm_content after the utm_content= ?

Generally, there is 12-13 fragments (splited by _) in my utm_content.

I would like to have this:

URL	utm_content
https:/www.xxxxxx.com/br/pt/yyyyy/example?origin=ALL&destination=ALL&utm_source=salesforce&utm_medium=email&utm_campaign=just_an_example_ok&utm_content=I_would_like_just_this_part_of_the_string	I_would_like_just_this_part_of_the_string

Any suggestions?

See example below

select url, 
  regexp_extract(url, r'utm_source=([^&]+)') as utm_source,
  regexp_extract(url, r'utm_content=([^&]+)') as utm_content
from your_table
