Importing files as elements
Hi all, I would like to populate one column of my table with XML files - meaning each element in that column will be an XML file. Is this possible and how can it be done? Would it be more efficient to store the files in the filesystem and instead keep a set of pointers as elements in that column that point to those files?

Re: sql to duplicate records with modified value
Hi Voytek You could try some variation of: INSERT INTO inserttable (user, maildir) SELECT REPLACE(user, '@', 'spam@') as user, CONCAT(maildir,'.spam/') as maildir FROM selecttable [WHERE ..] the where bit is optional of course! let me know how you go - hope you are keeping well! ray At 03:17 PM 27/03/2010, Voytek Eymont wrote: I have Postfix virtual mailboxes in MySQL table like below: I'd like to duplicate all records whilst MODIFYING two fields like so: current record has format like: user 'usern...@domain.tld' maildir 'domain.tld/usern...@domain.tld/' add new record that has: user 'username+s...@domain.tld' maildir 'domain.tld/usern...@domain.tld/.spam/' so that I'll end up with two record, existing, plus new one field 'user' - insert '+spam' ahead of '@' field 'maildir' append '.spam/' what's the best way mysql Ver 14.7 Distrib 4.1.22, for pc-linux-gnu (i686) using readline 4.3 Server version: 4.1.22-standard mysql> show tables; +---+ | Tables_in_postfix | +---+ | admin | | alias | | config| | domain| | domain_admins | | fetchmail | | log | | mailbox | | vacation | | vacation_notification | +---+ 10 rows in set (0.00 sec) -- Voytek -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=st...@tweek.com.au ( T W E E K ! ) PO Box 15 Wentworth Falls NSW Australia 2782 | p:+61 2 4702 6377 (Sydney/Penrith/Blue Mountains) | p:+61 2 4915 8532 (Newcastle/Hunter) | f:+61 2 8456 5743 | m:0414 270 400 | e:ray at tweek dot com dot au | w:www dot tweek dot com dot au 'What is more immoral than war?' - Marquis de Sade

I'm not sure where/how to start, the username is a primary index. or do I run a dump, then, work some script over dump, and, re-import ? -- Voytek -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org
