I want to use the Regexp_Extract function to isolate the first name from this string.

Full Name
Scott, John Smith
Jackson, Adrian Lee
Park, Julie Ann

Desired Output

John

Answer 1

You seem to want the first string after the comma. That would be:

select regexp_extract(full_name, ', ([^ ]+)') as first_name
