I have problem with regexp_replace ( PostgreSQL 8.3.1). Please try this
crappy string replacement:
select regexp_replace('abcd1235hgj!(at)#$^&^&*()-=', '[^0-9]*' ,'')
..and I get:
So only thirst assurance where removed, while documentation states that
"Replace substring_(s)_ matching a POSIX regular expression. ". I need
to get digits-only from any string. No sign or decimal point is needed.
I believe it's problem with my regular expression, as I am not very good
at it, thought it looks quite OK in Regex Coatch.
...or maybe there are way for 'no-errorous-blocking' casting? I could
easily skip strings witch could not be CAST'ed to bigint, but as long as
I get error and aborted transaction, I'm trying this approach.
Thanks for comments!
