I need to insert:
ALTER TABLE `theusers`  ADD `usergroup` ENUM('user','admin') NOT NULL DEFAULT 'user' AFTER `password`
It seems to me that every time I insert manually and close it forgets the query. Whether or not I save doesn't matter since it saves as an external file but no change is made.

If you need to know, I use PHP.

How am I going to be able to upload on my site to replace the old db?

So these are my 2 questions.
