I've a list of emails and a list of users (with emails). If the list of emails was already inside a table create table mails ( mail varchar(64) ); create table users ( name varchar(127), mail varchar(64) ); I'd do: select coalesce(u.mail, m.mail) from mails left join users on u.mail=m.mail; Now mails are into a php array and they may be in the range of 5000 but generally less. The final query will be something like insert into mailqueue (qid, uid, mail, ...) select ... and since some fields are pseudo random sequences computed from a serial, it would be "clean" to do it just in one query. Any clean technique? thanks -- Ivan Sergio Borgonovo http://www.webthatworks.it -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
