query to move 20,000 members to temp usergroup based upon userid

[Antivirus]

Is the following manual query safe to run to move a large amount of users to a different primary usergroup based upon their userid?

[SQL]
UPDATE user
SET usergroupid = 34
WHERE userid < 24509
[/SQL]

Just want to make sure nothing is missed (settings / data in other tables) when doing such thing through CP
Thanks!

Back up your forums first.

I did something like this the other week and it worked just fine.

already backed up[, just want to make sure the usergroupid doesn't need to be handled elsewhere. for instance, such as displaygroupid, user title, etc...

If you're using the default user title ladder, the usertitle field should be fine.

I hope that you know what you are doing, as the example you provided would move ALL users with a userid smaller then 24509 (including an admin with id = 1 for example???) to this new usergroup.

You should update the displaygroupid as well (if it's not '0' and is equal to their existing primary group).

Naturally, actually the query would be as follows:
[SQL]
UPDATE user
SET usergroupid = 34
WHERE userid < 24509
AND usergroupid = 2
[/SQL]

Ok, thanks that's what i was wondering, if there were any other values that should be updated in tandem.

Thanks to both of you
