Renaming of Users / Deleting Users? direct mysql manipulati

Postby iaw4 » Mon Sep 13, 2010 7:50 am

I have to change the naming scheme of users my system. Fortunately, I still have few enough users to be able to do this by hand. Alas, what is a good way to do this for 100 users?

I could go into the mysql data base and change the user id's. in a sense, this would be easiest, but I am worried that OJS uses the user name as a key elsewhere, and that this would totally hose my OJS system. can this be done?

I could retype every user's information into a new user, then merge it, and then double check that the merge was right. I would need to copy the required fields only. Rather inconvenient, but doable.


is direct mysql modification safe?

sincerely,

Hi iaw,

This should be fine, but you'll also have to change the passwords as the password is based on a hash of the username + the password. So in each case you change the username, you have to issue
Code: Select all
UPDATE users SET password=md5(concat('(new username')', '(new password goes here)')) WHERE username='(old username)';


Make sure you make a backup of your DB and do some tests to make sure your changes work alright.

Cheers,
Matt
