Subject: Extract only numbers from a varchar column
To: pgsql-general@postgresql.org
I need to extract only the first occurence of numbers from a column that is varchar.
Here are a few examples of what I need to do:
abc200xx -> 200
340ppsdd -> 340
150ytyty555 -> 150
Can this be done by a simple query or do I need to use a cursor?
Thanks
I've finally solved this way:
select name, regexp_replace(name, '\\D*', '', 'g')::int as replaced
from sometable
where regexp_replace(name, '\\D*', '', 'g') != ''
