Question

I need to migrate from my old user DB, to a new one…. but luckily the value of the password and salt fields are the same on both, but the column name are different (on old table:user passhash->secret, on new table:newuser password->salt)

How do I generate an insert dump from my existing users-data? Whenever I do something like

SELECT id,
  username,
LOWER(username) AS username_canonical,
  email,
  LOWER(email) AS email_canonical,
  passhash AS 'password',
  secret AS salt,
  1 AS enabled,
   'a:0:{}' AS roles,
   0 AS credentials_expired,
   0 AS expired,
   0 AS locked,
   uploaded,
   downloaded,
   torrent_pass,
   0 AS torrent_pass_version
FROM
  temp2.users AS fos_user
WHERE enabled = 'yes' ;

I can see the values correctly listed in phpMyAdmin…but when I export the results, I see inserts in the old structure:

INSERT INTO `fos_user` (`id`, `username`, `username`, `email`, 
    `email`, `passhash`, `secret`, `enabled`, `a:0:{}`, 
    `credentials_expired`, `expired`, `locked`, `uploaded`, 
    `downloaded`, `torrent_pass`, `torrent_pass_version`) 
VALUES....

Why not do the INSERT and SELECT at the same time with something like this:

INSERT INTO `fos_users` (username, password, salt ...)
SELECT LOWER(username), passhash, secret, ...
FROM users;

Of course this assumes that you can have the old dataset in the new database, at least temporarily…
