Hi all,
I am reading through some docs on switching to Postfix with a SQL
backend. The docs use MySQL but I want to use PgSQL so I am trying to
adapt as I go. I am stuck though; can anyone help give me the PgSQL
equiv. of:
SELECT
CONCAT(SUBSTRING_INDEX(usr_email,'@',-1),'/',SUBSTRING_INDEX(usr_email,'@',1),'/')
FROM users WHERE usr_id=1;
If the 'usr_email' value is 'person@xxxxxxxxxx' this should return
'domain.com/person'.
A direct conversion would be something like:
select split_part(usr_email, '@', 2) || '/' || split_part(usr_email,
'@', 1) from users where usr_id=1;
You could also do this:
select regexp_replace(usr_email, '(.*)@(.*)', '\2/\1') from users where
usr_id=1;
http://www.postgresql.org/docs/8.2/static/functions-string.html and
http://www.postgresql.org/docs/8.2/static/functions-matching.html are
the bits of the docs that cover these functions.
Cheers,

Thanks Steve!
Those look more elegant that what I hobbled together. :)
